Steady state accuracy specified in terms of:(a) Steady state error(b)

1.	Steady state accuracy specified in terms of:(a) Steady state error(b) Damping ratio(c) Natural frequency(d) All of the mentionedI 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» 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.
