Abstract

Mikhailov’s criterion states that a real Hurwitz polynomial of degree n satisfies the monotonic phase increase, that is to say the argument of goes through n quadrants as w runs from zero to infinity. In this paper, we utilize the generalized Mikhailov criterion presented in [1] to give a solution to the problem of finding the stabilizing feedback gains for a given linear-time invariant plant having a P controller, a PI controller and a PID controller.
