Unfalsified Control and Parameter Space Design of PID Controller

Abstract

In this paper, a data-driven design method of PID controllers is proposed based on unfalsified control concept. This method does not require constrcting a mathematical model for controller design. Therefore, this method can be applied to complex plants including nonlinear elements. A sharp estimate of the falsified region on the parameter plane can be obtained by the input-output responses of the plant excited by sinusoidal reference inputs for many frequencies.
