【Abstract】 The control system of the permanent magnet synchronous motor is multi-variable and non-linear. To solve the defects of the traditional PI control method,a RBF neural network based on-line discrimination and model reference self-adaptive control method for permanent magnet synchronous motors is proposed which achieves the adaptive control of the motor speed by using the outstanding non-linear mapping ability of RBF neural network and the off-line and on-line training of the neural network.Simulations show that the method has high control accuracy and good dynamic and static characteristics.更多还原
