Field oriented control of permanent magnet synchronous motor using predictive space vector modulation

This paper deals with two popular and powerful methods in electrical drive applications. The first one is the field oriented control (FOC) and the other one is space vector modulation (SVM). The proposed FOC-SVM method is incorporated with a predictive current control (PCC) technique. The suggested method estimates the desirable electrical torque to track mechanical torque at a reference speed of PMSM. The estimated torque is used to calculate the reference current based on FOC. In order to increase the performance of the traditional SVM a predictive current control (PCC) method is established as a switching pattern modifier. The performance of the controller is evaluated in terms of torque and current ripple and transient response to step variations of the torque command. The presented method has been verified with MATLAB-SIMULINK model. Simulation results confirm the ability of this technique in torque and speed ripple minimization and fixed switching frequency, simultaneously.
