PFC Design via FRIT with T-S Fuzzy Like Model for Discrete-Time Adaptive Control Systems

Abstract

This paper deals with a design problem of parallel feedforward compensator (PFC) via FRIT approach with T-S fuzzy like model data for discrete-time adaptive control systems. In order to obtain a desired PFC which realizes an ASPR augmented controlled system, PFC parameters are adjusted by the fictitious reference iterative tuning (FRIT) method so as to exist a feedback gain such that the output of the augmented closed loop system with the PFC track the output of the given SPR model by optimizing the performance function that consists of input-output data by T-S fuzzy like model.
