問題詳情

7. Consider the closed-loop feedback control architecture shown in Fig. 2, where P(s) is the open-loop plant,C1(s) and C2(s) are the feedback controllers, and H(s) is the transfer function from the reference r(t) to theoutput y(t), respectively. Assume that

and H(s) is asymptotically stable, which of thefollowing reference signal r(t) can be tracked by Hr(s without steady-state error?


(A) r(t) =sin(10t).
(B) r(t) = sin(20πt).
(C) r(t) = sin(0.1t).
(D)r(t)=sin(0.2πt).
(E) A 100 Hz triangular wave reference r(t).
