Question

A multi loop block diagram is shown in Figure AP9.10.

(a) Compute the transfer function T(s) = Y(s)/R(s).

(b) Determine K such that the steady-state tracking error to a unit step input R(s) = 1/s is zero. Plot the unit step response.

(c) Using K from part (b). compute the system bandwidth ω_b.
