Design of Fractional Order PI Controller for Permanent Magnet Synchronous Motor

This paper is concerned with the design of fractional order PI controller for permanent magnet synchronous motor based on the intelligent optimization algorithm. The implementation of fractional order differential operator and particle swarm optimization are briefly introduced firstly, and then the transfer function of permanent magnet synchronous motor is presented in the paper. Furthermore, the parameter tuning of fractional order PI controller based on improved particle swarm optimization is proposed. Finally, the simulation results show that the performance of fractional PI controller is superior to the integer order controllers.
