Question

Steady state error is usually specified in terms of :

(a) Error constants

(b) Damping factor

(c) Speed of response

(d) Bandwidth

The question was posed to me in a national level competition.

I'm obligated to ask this question of Preliminary Considerations of Classical Design in chapter Design of Control Systems

Answer 1

Correct option is (a) Error constants

To elaborate: Steady state error is the error that is specified as the time approaches infinite and value approaches the final value and specified mainly in terms of error constants that are mainly position, velocity and acceleration error constants.
