Question
The block diagram of a linear control system is shown in the Fig, where
r(t) is the reference input and n(t) is the disturbance.
a) Find the steady-state VALUE of e(t) when n(t)= 0 and r(y) tus(t). Find
the conditions on the values of and K so that the solution is valid
Use MATLAB:
b) Constrct the root loci for K>=0 with = 1. Analyze the result
c) Construct a Bode plot and analyze the phase margin and gian
margin
d) Construct the Nyquist Diagram and analyze the system stability
e) Show the system response to a unit step command for n(t0= 0 and
a unit step disturbance input for r(t)
