Posted by AndrewShinko on Sun 07 of Dec, 2008 21:40 EST Seconded. Also, we’ve only had one example on designing a controller using gain and phase margins - nothing really in regards to homework or what not. Should we expect that tomorrow as well?
Posted by D. Dane Quinn on Sun 07 of Dec, 2008 22:29 EST The polar plots come directly from the Bode plots which, for any frequency omega, identify the amplitude and phase of the transfer function. There will be frequency response problems on the exam, but I will take into consideration both the length of the exam and the time that we spent on these problems. You should however definitely be able to calculate gain and phase margins for a given system.

More or less I’m asking if we need to spend a lot of time looking at that example you did in the last week of class whereby we had to design a controller for a bode plot (the one where we had to change the phase and Kv)
