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.

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...

very clear and useful video. thank you professor

Sir, you are the best, thank you so much for the very helpful video.

[mahar_vlogs]

very informative for masters students thanks for sharing :)

[engineeryou]

a very very good and helpful video. thank you so much!

[ricardoentz]

thank you for your video.that was a nice refresher from university classes!

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?

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.

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?

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?

Sir, how do I apply a LQR controller in MIMO system in simulink?

[faijalmeman]

sir why u r solveing it by matalab., can you solve it step by step

[pankajymca]

hi sir how can i find the desired poles, how i know this is desired poles for me please reply sir
