Dr. Yiza Srikanth Reddy 0:03:21
MI professional journey UH is now winding as a postdoc at Kenwood National University, South Korea.
Dr. Yiza Srikanth Reddy 0:03:26
So where are my current focus? Research area? Is data-driven predictive?
Dr. Yiza Srikanth Reddy 0:03:29
Controller design for wind turbine.
Dr. Yiza Srikanth Reddy 0:03:32
No detection and wind up and control.
Dr. Yiza Srikanth Reddy 0:03:42
So prior to my before my post work experience, I finished my PhD at same university University, South Korea.
Dr. Yiza Srikanth Reddy 0:03:57
So in my during my PhD, during six years of my PhD journey, so I try to design, I I tried many advanced control designs.
Dr. Yiza Srikanth Reddy 0:03:59
For winter belt reduction and controlling of winter by especially winterbine site.
Dr. Yiza Srikanth Reddy 0:04:08
So where we are mainly focusing on design of controllers, advanced controllers where we can test the controllers in real time simulation.
Dr. Yiza Srikanth Reddy 0:04:12
Which is very popular in industry.
Dr. Yiza Srikanth Reddy 0:04:28
Through being with Jihad software and open source NRL open past. So with these two softwares we are validating the controllers in real time. So thereby we can extend those controllers in realistic way but.
Dr. Yiza Srikanth Reddy 0:04:31
In in real way, we have to do like that.
Dr. Yiza Srikanth Reddy 0:04:35
Simulation in wind turbine design. Winter band control.
Dr. Yiza Srikanth Reddy 0:04:56
So prior before before joining PhD so I worked as assistant professor. One is Hyderabad VNR Vijit and one is Nevada University Rajasthan where I used to teach the students like microcontrollers control system.
Dr. Yiza Srikanth Reddy 0:04:58
And basically critical engineering this subjects I taught to students and I gated.
Dr. Yiza Srikanth Reddy 0:05:03
Like UH PG students and Btech students.
Interviewer 0:05:02
Thank you for
Dr. Yiza Srikanth Reddy 0:05:12
Yeah. Yes. Thank you.
Dr. Yiza Srikanth Reddy 0:05:23
Yeah.
Dr. Yiza Srikanth Reddy 0:05:26
Yeah.
Interviewer 0:05:41
Let's begin by discussing your expertise in Power Electronics, Power Systems, or Control Systems. Could you describe a specific project or research achievement that highlights your expertise in one of these areas?
Dr. Yiza Srikanth Reddy 0:05:57
My expertise is control system. Specifically, we design advanced controllers for wind turbines, especially wind turbines like onshore and offshore turbines. We are dealing with onshore and offshore turbines.
Dr. Yiza Srikanth Reddy 0:06:02
So we are basically most focusing on control system.
Dr. Yiza Srikanth Reddy 0:06:04
In application to wind turbines.
Dr. Yiza Srikanth Reddy 0:06:09
Yeah.
Dr. Yiza Srikanth Reddy 0:06:19
Yeah.
Dr. Yiza Srikanth Reddy 0:06:33
Yes, yes. So we are mainly focusing on uh, like LKG controllers, linear quadratic chain controllers, model predictive controllers and H Infinity controllers.
Dr. Yiza Srikanth Reddy 0:06:37
So we test these controllers on Unshare, Turbine 5 MW and Ariel.
Dr. Yiza Srikanth Reddy 0:06:44
Uh, find me out denial open first turbine and uh, super jump in five MW turbine.
Dr. Yiza Srikanth Reddy 0:06:56
So we test the controllers on these turbines realistically like we do the simulation software in the simulation loop.
Dr. Yiza Srikanth Reddy 0:06:59
We we do first design the controllers in Matlab.
Dr. Yiza Srikanth Reddy 0:07:17
Unlinear model once the model is I mean the once the linear controller is perfectly fine in Matlab. So we shifted those controllers linear controllers to apply full nonlinear 5 MW model wind turbine model.
Dr. Yiza Srikanth Reddy 0:07:29
So which we can do by using coded all the controllers in C++ to test the controllers and turbine. So which we do in software in the loop that is DNV graded software.
Dr. Yiza Srikanth Reddy 0:07:40
So there we can test the control design on real time, real time term by. So this is the process generally we do in.
Dr. Yiza Srikanth Reddy 0:07:48
The industry side as well. So this is the way we do the advanced control designs. One is the MPC and one is LQG and HMD.
Dr. Yiza Srikanth Reddy 0:07:52
In just in comparison with standard π controllers.
Dr. Yiza Srikanth Reddy 0:08:10
Yes.
Interviewer 0:08:21
Can you describe your approach to teaching a complex concept in control systems to undergraduate or graduate students who may not have a strong background in the subject?
Dr. Yiza Srikanth Reddy 0:08:30
So, uh, if we uh, any student don't have any experience of control system.
Dr. Yiza Srikanth Reddy 0:08:36
So first we basically teach the basic concepts of control system.
Dr. Yiza Srikanth Reddy 0:08:40
So what is the system? How we can model it?
Dr. Yiza Srikanth Reddy 0:08:42
So after that modeling.
Dr. Yiza Srikanth Reddy 0:08:44
Yeah.
Dr. Yiza Srikanth Reddy 0:08:50
Hello, got it.
Dr. Yiza Srikanth Reddy 0:09:03
Yeah.
Dr. Yiza Srikanth Reddy 0:09:33
Ya, once we designed the I mean modeling. So because these advanced controllers first we need to know the modeling. So once we know the model because these controllers basically depending on modeling. So if you know the modeling perfectly then we can take the model in terms of state space or transfer function model. So with that model we can design the linear controllers in terms of modeling like MPC basically used state space model.
Interviewer 0:09:02
How do you transition from basic modeling concepts to more advanced topics, such as designing controllers like LQG or MPC, for your students?
Dr. Yiza Srikanth Reddy 0:09:35
So to design the controller no.
Dr. Yiza Srikanth Reddy 0:09:47
So in that way I can teach the students how to modeling in simple way like taking the differential equations and then convert into.
Dr. Yiza Srikanth Reddy 0:10:06
Frequency domain like transfer transfer function modeling or I mean time domain like state space modeling. So this way first I need to tell the students designing of modeling. Once we design the modeling we need to design the controllers whether the system is like.
Dr. Yiza Srikanth Reddy 0:10:16
Getting the desired characteristics, so performance in terms of stability. So we design the controllers by using MATLAB simulink by using border plot.
Dr. Yiza Srikanth Reddy 0:10:43
Language plot so with these techniques, uh, we can design the controllers once we achieve the performance and like characteristics like rise time, cycling time. So these things we are like step response. How is the step response look like? So based on this photo plot, how we can design the controller? What is your design requirements So with this all this.
Dr. Yiza Srikanth Reddy 0:10:46
This, with all these things we can keep in mind.
Dr. Yiza Srikanth Reddy 0:11:18
Based on that we have to design the controllers. After designing the controller we have to reach the performance of the controller whether it is reaching the required desired characteristics or not. Once it is preaching the desired characteristics then that control is perfectly fine. We can go with software in the simulation look like we can test either it is in MATLAB and whether it is in any other software simulation.
Dr. Yiza Srikanth Reddy 0:11:22
Once if it is OK if we can go for deployment in the hardware.
Dr. Yiza Srikanth Reddy 0:11:29
Yeah.
Interviewer 0:11:28
Thank you, Dr. Reddy, for that comprehensive explanation. You've demonstrated a
Interviewer 0:11:41
Next, let's discuss your experience with student evaluation and exam duties. Can you share how you approach designing fair and effective assessments for your students?
Dr. Yiza Srikanth Reddy 0:11:52
Uh, I like, I can assist the students performance in terms of uh.
Dr. Yiza Srikanth Reddy 0:12:24
In my point of view, uh, rather than giving an assignment like, uh, simply copy paste from the ChatGPT or some other textbooks. So instead of that, uh, if you design any new problem like, uh, in terms of MATLAB simulation or in terms of any coding. So if we give the like coding in terms of, uh, testing the students, even though they don't.
Dr. Yiza Srikanth Reddy 0:12:27
How to code if they get to learn how to?
Dr. Yiza Srikanth Reddy 0:12:46
Code it or how to do the simulation step by step. So once if we get to know familiarization these all those things so we can evaluate the students performance like whether he can able to.
Dr. Yiza Srikanth Reddy 0:12:52
Learn all those things or not that only I can test instead of simply copy pasting from other AI tools or other any textbooks.
Dr. Yiza Srikanth Reddy 0:13:01
If you if you give like in the direction of what you can say thinking and.
Dr. Yiza Srikanth Reddy 0:13:09
How the system is performing? Like validating the system in terms of what you can say.
Dr. Yiza Srikanth Reddy 0:13:08
Thinking and.
Dr. Yiza Srikanth Reddy 0:13:37
In terms of like the student thinking ability, based on that I can evaluate each student performance in not in terms of any simply copy pasting assignments. In this way I can assess my student and I can increase their confidence level so that they can easily get the like in future wherever they go. They can easily get the jobs in companies as well.
Dr. Yiza Srikanth Reddy 0:13:47
Yes.
Interviewer 0:14:00
Let's now discuss your ability to guide student projects and research. Could you provide an example of a project you have guided, or how you would typically support students in their research endeavors?
Dr. Yiza Srikanth Reddy 0:14:07
Yahweh. Basically I can uh, guide the students in terms of like, uh.
Dr. Yiza Srikanth Reddy 0:14:10
In terms of feeding everything.
Dr. Yiza Srikanth Reddy 0:14:42
Like I can guide them, you better search in this direction. You better do this way you can think in this way. So so that we can just give the directions to the students. So in terms of research, if they struck while they are doing any project or any like research oriented simulations, anything then I can get them to. Test in this direction testing this.
Dr. Yiza Srikanth Reddy 0:14:55
In this way you do you do this way like that. I want to 1st initialize the students to get to know all the research abilities.
Dr. Yiza Srikanth Reddy 0:15:24
So that they can easily go through the all the materials, all the like papers so that they can easily learn and they they have to do by themselves. So supervisor can do only supervision. So they will not teach everything like a putting banana in mouth. So in my point of view, every supervisor should supervise like in terms of whether they get any doubts.
Dr. Yiza Srikanth Reddy 0:15:30
So you like they have to do by their own hand, they they have to do by own ability with their own ability.
Dr. Yiza Srikanth Reddy 0:15:49
Then they can achieve good results in their research. So supervisor in terms of my opinion, they should mainly focusing on supervision. When they get stuck in their project, we have to give the ideas so that students can access in that research areas.
Dr. Yiza Srikanth Reddy 0:16:02
Yes.
Interviewer 0:16:00
Thank you, Dr. Reddy. Your emphasis on guiding students while encouraging autonomy and independent problem-solving is both effective and motivating for young researchers.
Interviewer 0:16:15
Now let's turn to your communication and teaching approach. How do you ensure your explanations and lectures are structured in a way that students of varying levels of understanding can follow effectively?
Dr. Yiza Srikanth Reddy 0:16:19
Could you please repeat?
Interviewer 0:16:30
Certainly. How do you ensure that your explanations and lectures are well-structured, so that students with different levels of understanding can follow along effectively?
Dr. Yiza Srikanth Reddy 0:16:38
OK, yeah. Uh, I basically teacher like, uh.
Dr. Yiza Srikanth Reddy 0:16:41
In very like, uh.
Dr. Yiza Srikanth Reddy 0:16:56
Basic level First I will start with the basic level so everyone can understand very easily like simple mathematics like what the subject made and I use single basic English so that everyone can understand.
Dr. Yiza Srikanth Reddy 0:17:26
So I can follow like what you can say realistic examples with realistic examples. If you map with realistic examples nature because every engineering application inspired from nature if you correlate with nature. So student can easily understand without any boy hurting. So that is the my way of explanation. Even I taught students while I was doing.
Dr. Yiza Srikanth Reddy 0:17:31
Professor in my academic journey.
Dr. Yiza Srikanth Reddy 0:17:58
So I generally basically follow mostly like student friendly oriented. Like whether they're understanding or not. I'll follow regularly follow up if anyone can understand. I can spend some time with them even beyond that teaching hours if anyone interested so that I can teach them if they are not understanding the classroom.
Dr. Yiza Srikanth Reddy 0:18:16
If they're ready so I'm I can ready to teach them anytime everywhere even in on the phone as well. So but in my point of view, so teaching isn't like two way learning process from student and teacher side. So it's like a two way.
Dr. Yiza Srikanth Reddy 0:18:47
So, so that it can be improved for teachers and students so that we can learn from students and students learn from teacher. So it's a two way process. Then only like it will be more effective and they can easily understand. They can easily mingle with teachers without fearing any like without fearing. So my point of view is teaching nothing but.
Dr. Yiza Srikanth Reddy 0:18:52
We should teach them in terms of.
Dr. Yiza Srikanth Reddy 0:18:54
How they're like learning.
Interviewer 0:18:57
Thank
Dr. Yiza Srikanth Reddy 0:19:00
How we are teaching.
Dr. Yiza Srikanth Reddy 0:19:04
In in like it's like a completely like.
Dr. Yiza Srikanth Reddy 0:19:25
Nature related teaching. So if we tell them like nature based examples then they can easily understand too much mathematics not required to understand initial basics. So that once they are getting to this understanding memorization of basic mathematics so that in future they will excel and then they can learn more.
Dr. Yiza Srikanth Reddy 0:19:27
Better.
Interviewer 0:19:40
Thank you, Dr. Reddy. Your nature-inspired, student-friendly teaching approach demonstrates a deep commitment to making complex topics accessible and fostering a collaborative learning environment.
Interviewer 0:20:31
Sorry to interrupt, we're down to the last 5 minutes.
Dr. Yiza Srikanth Reddy 0:20:48
Is it finished?
Dr. Yiza Srikanth Reddy 0:20:53
Yeah, yeah.
Dr. Yiza Srikanth Reddy 0:20:58
Yeah.
Interviewer 0:21:08
Could you briefly share a significant research publication of yours and the impact or contribution it has made in your field?
Dr. Yiza Srikanth Reddy 0:21:13
Uh, you want me to?
Dr. Yiza Srikanth Reddy 0:21:16
Tell how many publications I have.
Dr. Yiza Srikanth Reddy 0:21:31
Yeah, yeah. My one significant publication is comparison of controllers for a wind turbine.
Dr. Yiza Srikanth Reddy 0:21:55
Under different turbulent conditions and gas wind conditions, where I mainly focus on designing of advanced controllers, I as I mentioned earlier, model predictive controllers and HMT controllers in comparison with PE controllers under different turbulent conditions, under different guest conditions, how it is that controller is effectively.
Dr. Yiza Srikanth Reddy 0:22:04
Working or not? So in this way I'm just to compare comparing the controllers. So which controller is outperforming on what?
Dr. Yiza Srikanth Reddy 0:22:28
On what basis we are it is outperforming. So here we are mainly basically design the controllers. As I mentioned first it is in the controllers on linear model. After that we shifted to full nonlinear model. So we do generally basically we do simulation like that.
Dr. Yiza Srikanth Reddy 0:22:50
There we can understood MPCS outperforming with H Infinity and PA controllers. So in terms of guest, especially guest during guest conditions, this MPC is with the like we mainly focusing on feed forward design also by using the Lidar based wind speed, so that wind speed we are feeding to the.
Dr. Yiza Srikanth Reddy 0:22:58
MPC controllers so that we are minimizing that guest on turbine.
Dr. Yiza Srikanth Reddy 0:23:17
So so that it will generate speed oscillations every like decreased without increasing pitch activity so that we can pitch thereby we can increase the lifetime of pitch actuators.
Dr. Yiza Srikanth Reddy 0:23:18
So this is the main my significant contribution towards my research.
Interviewer 0:23:38
Thank you, Dr. Reddy, for sharing. Your research on advanced controllers for wind turbines, especially leveraging lidar-based wind speed predictions to enhance performance and prolong actuator lifespan, is indeed impactful in the field of control systems and sustainable energy.
Dr. Yiza Srikanth Reddy 0:23:51
Obviously because we really like Redis, increase the lifespan of I cheated so that lifetime of turban will increase.
Dr. Yiza Srikanth Reddy 0:23:46
Yes.
Dr. Yiza Srikanth Reddy 0:24:05
Yes.
Interviewer 0:24:20
Finally, Dr. Reddy, let's discuss your experience with industry projects or consultancy. Could you share an example where your expertise was applied to solve a real-world problem in collaboration with the industry?
Dr. Yiza Srikanth Reddy 0:24:24
Women in future.
Interviewer 0:24:33
Could you clarify what you mean by "women in future"? Are you referring to a specific project, or would you like to provide an example?
Dr. Yiza Srikanth Reddy 0:24:46
No, no, he uh, like, uh, it's uh, you're asking about whether I have any experience with the consultancy projects, any industry project like that you are asking.
Interviewer 0:24:57
Yes, precisely. Could you share an example of any consultancy or industry project where you applied your expertise to address real-world challenges?
Dr. Yiza Srikanth Reddy 0:25:08
Yeah, uh, like my expertise, like we can, uh, apply to, as I mentioned, uh, for wind turbines is like a.
Dr. Yiza Srikanth Reddy 0:25:21
Sustainable gender power generation. So like we can mainly if we decrease the loads and turbines.
Dr. Yiza Srikanth Reddy 0:25:28
So that it can sustain more years, so life span will increase so that without interrupting any power generation.
Dr. Yiza Srikanth Reddy 0:25:34
So we, uh, we, uh, this expertise, uh, I can use for, uh.
Dr. Yiza Srikanth Reddy 0:25:38
In these areas.
Dr. Yiza Srikanth Reddy 0:25:51
Yeah.
Dr. Yiza Srikanth Reddy 0:25:55
