11. Consider the system shown in Fig. 4.29 which represents control of the angle of a pendulum that has no damping, (a) What condition must Dc(s) satisfy so that the system can track a ramp reference input with constant steady-state error? (b) For a transfer function Do(s) that stabilizes the system and satisfies the condition in part (a), find the class of disturbances w(t) that the system can reject with zero steady-state error.
