Consider the PD control system shown in Figure 10.7.1. Suppose that I = 25 and c = 5. The specifications require the steady-state error due to a unit-step command to be zero and the steady-state error due to a unit-step disturbance to be no greater than 0.2 in magnitude. In addition, we require that ζ = 0.707. Compute the required values of the gains, and evaluate the resulting time constant.
