Abstract:

This paper first proposes the establishment of PMSM mathematical model.Then,the conventional PID control is discussed to achieve PMSM control system by using an incremental PID.The learning ability of RBF neural network offers adaptive PID controller parameter to improve the performance of PID controllers.The particle swarm optimization (PSO) is also proposed to improve the performance of RBF network in.The simulation results indicate that the mode control system based on RBF neural network can improve the performance of PID controller compared with conventional PID control with higher convergence speed and tracking accuracy of PMSM control system.
