A unity feedback system has been operated for 5 years and need to be evaluated. It has an open loop transfer function as follows: k G(s) s(s + 1)(s+3) When the system is operating at 4.32% overshoot to a unit step input, its dominant closed loop poles are located at -0.42 j0.42. a) Calculate the value of damping ratio and K at this instance. b) Design a suitable PD controller so that the system will produce a new settling time of T,= 2.86 s while maintaining the same percentage of overshoot as before.
