- 6. The unity feedback system shown in Figure P9.1 with K(s+6) G(s) (s+2)(s + 3)(s + 5) is operating with a dominant-pole damping ratio of 0.707. Design a PD controller so that the settling time is reduced by a factor of 2. Compare the transient and steady-state performance of the uncompensated and compensated systems. Describe any problems with your design. [Section: 9.3]
