If the performance index of a phase lead compensator is (s+a)/ (s+b) and that of a lag compensator is (s+p)/(s+q), then which one of the following sets of conditions must be satisfied?
(a) a>b and p<q
(b) a>b and p<q
(c) a<b and p<q
(d) a<b and p>q
I got this question in an online interview.
My question is from Performance Indices topic in division Time Response Analysis, Design Specifications and Performance Indices of Control Systems
