【Abstract】 Design of fractional order PI controller for permanent magnet synchronous motor is investigated based on intelligent optimization algorithm. The simulation of fractional differential operator and particle swarm optimization are introduced firstly, and then the transfer function of permanent magnet synchronous motor is presented. Furthermore, the parameter tuning of fractional PI controller based on improved particle swarm optimization is proposed. The simulation results show that the performance of fractional PI controller is superior to the integer order controller.更多还原
