System Dynamics and Control: Module 17 - Root Locus Basics

[@Binancian]

Your presentations and the structure of them are very clear and neat, thank you sir. It would be great that you make some more presentations about stability criteria like Nyquist and Hurwitz ect.

Thank you so much for your clear explanation!! 😄

Thank you so much for your explanation!!

Which one book do you refer (for the equation that provides de location to "break-out point") @1:10:05?

[@hillrickc]

Matheus Oliveira Momolli I use the book "System Dynamics" by Ogata, but most any introductory controls textbook will have such an equation.

Rick Hill Thank you.

Hi sir!! module 15 missing!! Great lectures

Hello Rick Hill, every minute of this modules were useful and it helps to learn about root locus. BUT can you upload a video on calculation of Angle or phase and magnitude with out using MATLAB?? If yes then that would be more helpful.

Hi, thanks for uploading these modules, they’re really helpful! I have a question - What would be the zeros of an OLTF which does not contain s in its numerator? eg. 50K/((s+8)(s^2+4s+29)) Also, since there are 3 poles to this, will that mean there must be 3 zeros (some/ all of which asymptotic)? Any help would be much appreciated, cheers!

I am glad you find the modules helpful. Since there are no s terms in the numerator, this transfer function has no zeros. This combined with the fact that it has 3 poles (3 more open-loop poles than open-loop zeros) means that it will have 3 asymptotes (which I refer to as "zeros" at infinity). Hope that helps.
