A New Design of Speed Controller of PMSM Based on Model Reference Fuzzy Adaptive Control Method

A method for the speed controller design of permanent-magnet synchronous motor(PMSM) is proposed, which is based on the model reference fuzzy adaptive control(MRFAC) approach. As an intelligent control technology, fuzzy logic control is a mathematical model-free control technique and provides a systematic method to incorporate human experience and implement nonlinear algorithms, characterized by a series of linguistic statements, into the controller. In this paper, two fuzzy logic inference systems are used here. One is employed as main controller for substituting the feedback controller in the MRAC, and the other is used to form the fuzzy adaptive mechanism with special adaptation algorithm. The simulation results are illustrated to show very good static and dynamic performance with moment of inertia parameter and load variations.
