You are God send. Thank you so much

Hello Prof., Great lectures. Which Textbook to refer for this topic to know more?

[@MAFarooqi]

Thanks Prof.

Hello, Prof. Thank you for the good work. Please, how can the boundary be defined? i working on DFIG and I am having issues determining the control constant

[@MAFarooqi]

You have to determine upper bound on the uncertainty. For that purpose, you will need upper bound on the uncertain parameters of DFIG.

@@MAFarooqi Thank you Prof. Please what are the conditions for defining the boundary uncertainties. Do you have recommended material that can help me in better this. I'm stuck in my current research because assume coefficient constant I'm using is not giving me a good performance. Please recommend a material that could and rule of thumbs in assigning boundary uncertainty parameters

[@MAFarooqi]

Are you talking about the simulation results or practical implementation results? If practical implementation, you may increase the value of the gain to see the results.

Do you mean inverted pendulum? Why do you need to bring a pendulum states to 0 with control? it will do that on its own unless you are trying to describe an inverted pendulum.

[@MAFarooqi]

You are right, the pendulum states would go to zero without application of any control. The objective of the example was to demonstrate the design procedure of SMC. Furthermore, the design procedure to stabilize the pendulum at any other point, for example the upright position or the horizontal position, is exactly the same.
