P6) A closed-loop feedback system is shown in Figure 5. (a) Obtain the Nyquist plot and determine the phase margin. Assume that the time delay T=0 s. (b) Compute the phase margin when T =0.5+10 'n s (n=the student's number in the group notebook). (c) Determine the minimum time delay that destabilizes the closed-loop system.
