A robot tennis player is shown in Figure DP9.4 (a), and a simplified control system for θ2(t) is shown in Figure DP9.4(b).The goal of the control system is to attain the best step response while attaining a high Kv for the system. Select Kv1 = 0.4 and Kv2 = 0.75, and determine the phase margin, gain margin, bandwidth. percent overshoot, and settling time for each case. Obtain the step response for each case and select the best value for K.
