Permanent Magnet Synchronous Motor Direct Torque Control Based on Radial Basis Function Network

The basic theory of direct torque control(DTC) of permanent magnet synchronous motor(PMSM) is analyzed and then a novel radial basis function neural networks controller is presented. The neural networks structure design, learning samples and training algorithms are expounded. A conventional switching table of permanent magnet synchronous motor direct torque control is used to train radial basis function neural network. The controller could quickly select an output vector and the system using this neural networks controller has quickly parallel speed and high torque response. The simulation of the permanent magnet synchronous motor shows the effectiveness of the control scheme.
