C-3) Figure C-3 is the Bode diagram of a certain G(s). What is the expression for G(s)? C-4) Given K ± 1 ² s ³ 2 ± ³ s G ± 1 ´ s ³ 2 a) Sketch the Nyquist plot and the root locus for k>0 and k<0. For the Nyquist plot use G(s)/k. Clearly show 0+, +j f , -j f , 0- and the direction of increasing frequency. b) There will be four regions of interest (A,B,C,D left to right) in the Nyquist plot. Mark them. c) Show the r ´ O branches which correspond to regions B and D. C-5) Estimate the phase margin and crossover frequency specifications to which a loop gain

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
