P10.6 Repeat Problem P10.5 by using a phase-lead compensator and compare the results.

Data From in P10.5 A stabilized precision rate table uses a precision tachometer and a DC direct-drive torque motor, as shown in Figure P10.5. We want to maintain a high steady-state accuracy for the speed control. To obtain a zero steady-state error for a step command design, select a proportional plus integral compensator. Select the appropriate gain constants so that the system has a percent overshoot of P.O. = 10, and a settling time (with a 2% criterion) of Ts … 1.5 s.
