I would be so lucky to have any professor like you in my university, really willing to teach, thanks a lot and keep it up...Good thing about this content, is that 3 years later you are still helping people from everywhere!! Just don't come to Spain, 90% of enginyer professors don't give a f*** about teaching and then wreck you in the exam...that's the education philosophy here...
This video very usefull fto understand controller design in ss domain .. it will be effective if kindly share the design of controller of delayed system in ss domai.
Sir, what if i have 5x5 [A] and only 4x1 [B] inputs and 1x4 [C] outputs. This is because i would need to adjust 5 knobs to correct 4 outputs. How do i deal with that?
I like pole placement and the instructor shows how to calculate the gains in a simple example. The instructor does not say what K1, K2 and K3 are. K1 is the proportional gain, K2 is the derivative gain and K3 is the second derivative gain. In reality using the derivative gain is noisy. Using the second derivative gain is almost impossible due to noise and sample jitter. I object! Using Matlab will provide answers without understanding. Some how this is called teaching. I would want to know how to write the code in Matlab that generates the answers. Also, what do you do if the controller needs an integrator? The instructor should relate this do a problem in the real world. For instance in motion control the states are usually position, velocity, acceleration and some times jerk In temperature control there is the temperature, the rate of change of the temperature and sometime the second derivative of the temperature. Finally at about 22 minutes the instructor address the problem of not having an integrator. The instructor is correct in that the integrator acts on the error. I would like to see this applied to a real system. I find using matrices are non-intuitive. I prefer writing the functions using Laplace transforms or differential equations. This way you can see how the variables affect the response. Where does the plant or open loop transfer function come from?
hi sir, I've got a question on the quadruple tank system, I have constructed a PI controller using LQR function instead of the place function, mainly because I wanted to be able to tune the q and r to be able to attain realistic control voltages. the project calls for implementation of the PI controller on the nonlinear system (THIS IS WITH INTEGRATORS, RAW CONSTRUCTION FROM THE DIFFERNTIAL EQUATIONS ON SIMULINK), I'm currently having problems implementing it and I could use some help?
Thanks for the help. I just did an exam using this video. Keep up the kind work.
I can not express that how helpful this lecture is. It helped me a lot.

Many thanks for your kind words.
che que bo!! un comentari aixi nomes podia venir d'un televident local
Sir, you are the best, thank you so much for the very helpful video.
Thanks for your kind comment. I will be teaching online regularly at ETI-London.uk
very clear and useful video. thank you professor
Thank you... Very much helpful sir..
a very very good and helpful video. thank you so much!
very informative for masters students thanks for sharing :)
Thanks a lot professor.....................
Very helpful video sir!
THANK YOU SIR.
thank you for your video.that was a nice refresher from university classes!

+iRaQzLoVeR Glad to be of help.
Sir, how do I apply a LQR controller in MIMO system in simulink?
Bless you
love u sir
thanks sir :)
sir why u r solveing it by matalab., can you solve it step by step
thanks
hi sir how can i find the desired poles, how i know this is desired poles for me please reply sir
By considering system desired performance, like percent overshoot, raise time , settling time etc
شكرا أستاد
