MODEL-FOLLOWING PID CONTROL USING HYPERSTABILITY THEORY

A model-following control (MFC) using proportional-integral- derivative (PID) compensator for a nonlinear plant is described. The reference model in this paper is chosen as a PID control system. This provided a very useful guide for selecting a reference model. In this article, a modified MFC system is developed via the hyperstability theory. A new control algorithm is proposed whereby the supplementary loop generates a correction signal and is superposed on the conventional PID control signal to ensure the performances of the MFC. When the supplementary loop signal is null, the MFC system is the conventional PID control system.
