Research on Chaotic Motion Simulation Method of Fractional Order Permanent Magnet Synchronous Motor

Abstract

Fractional order permanent magnet synchronous motor (PMSM) has fractional order, so it is difficult to simulate the fractional PMSM system because the usual Matlab can only simulate the integer order differential system. Firstly, the fractional order mathematical model of permanent magnet synchronous motor is introduced in this paper. Secondly, the calculation method of fractional order calculus is studied. Finally, the simulation model of fractional order PMSM is built by using this method, and its chaotic phase diagram is also given. The simulation results show that the proposed simulation method is effective.
