1.	PD controller is used to compensate system. Compared to the uncompensated system, the compensated system has:(a) A higher type number(b) Reduced damping(c) Higher noise amplification(d) Large transient overshootI got this question by my college director while I was bunking the class.I'm obligated to ask this question of Cascade Compensation in Frequency Domain in portion Design of Control Systems
Answer» The correct OPTION is (c) Higher noise amplification To explain I would say: Proportional Derivative CONTROLLER is used to increase the BANDWIDTH and also increases the signal to noise RATIO by REDUCING the noise and increasing the signal.
