Turn in a MATLAB generated Bode plot for ) 68 4 ( ) ( 2 s s s K s KL where K is set to the positive value determined in problem 2. at which roots cross over into the right half plane, i.e., roots on the imaginary axis. Estimate from your Bode plot the frequency at which the magnitude of the response is 1.0 (0 dB) and the angle of the response is 180 o . 5. A certain system has a controller: 8 1 ) ( s s D c a) Assume the sampling rate T is 10% of the controller time constant. Find approximate expressions for D c [z] for a digital realization of the controller using: Tustins method Eulers method b) Find a difference equation relating controller output to controller input for the D c [z] you found using Tustins method....
