Question

PID controller:

(a) Decreases steady state error and improves stability

(b) Rise time decreases

(c) Transient response becomes poorer

(d) Increases steady state error

This question was addressed to me by my school teacher while I was bunking the class.

I need to ask this question from Cascade Compensation in Time Domain topic in chapter Design of Control Systems

Answer 1

Right option is (a) Decreases steady state error and improves stability

To elaborate: Proportional Integral and Derivative controller is the controller that is the combinational controller that increases the speed of response, decreases steady state error and improves stability.
