The steady state error of the system with a forward path transfer function G(s)=13(s-1)/(s-1) and with a parabolic input is _______(a) Infinite(b) 0(c) -Infinite(d) UndefinedI have been asked this question in an interview.My doubt is from Time Response of Control Systems in section Control System Applications of MATLAB

Answer»

Correct option is (a) Infinite

Easy explanation: The given system has no poles at s=0. This means that for a parabolic INPUT, the parabolic ERROR constant is 0. HENCE, the STEADY state error will go to infinity. Thus option Infinite is correct only.
