Question

Steady state accuracy specified in terms of:

(a) Steady state error

(b) Damping ratio

(c) Natural frequency

(d) All of the mentioned

I had been asked this question by my school teacher while I was bunking the class.

My doubt is from Effect of Adding a Zero to a System and Design Specifications of Second-order Systems topic in chapter Time Response Analysis, Design Specifications and Performance Indices of Control Systems

Answer 1

The correct answer is (a) Steady state error

For explanation I would say: Steady state accuracy entirely depends on the accuracy of steady state which is determined by steady state error which is the difference between the final output and desired output.
