Consider the system shown in Figure 8–52. Design a compensator such that the static velocity
error constant is 4 sec−1
, phase margin is 50°, and gain margin is 10 dB or more. Plot unit-step and
unit-ramp response curves of the compensated system with MATLAB.Also, draw a Nyquist plot
of the compensated system with MATLAB. Using the Nyquist stability criterion, verify that the
designed system is stable.
