This paper presents a simple but effective method for designing robust PI or PID controller. The robust PI/PID controller design problem is solved by the maximization, on a finite interval, of the shortest distance from the Nyquist curve of the open loop transfer function to the critical point-1. Si
The constraints on the PID gains, which are derived from the H norm performance index by discretization of the frequency, are convex or concave depending on frequencies. This problem is a non-convex problem, and a new method of approximating these constraints as adequate linear inequalities is propo
