Simulation of Model Predictive Control – Space Vector Modulation fed PMSM drive

Abstract

To achieve high dynamic torque control for Permanent Magnet Synchronous Motor (PMSM) drives, a Model Predictive Control (MPC) scheme is introduced in this paper. The basic idea of MPC is to predict the future behavior of control variables in the time domain based on the model of the control system and choose the control action according to an optimization cost function. This work proposes a Model Predictive Control-Space Vector Modulation (MPC-SVM) technique for PMSM drives, combines the advantage of both SVM technique and MPC, which overcomes the problem of high ripple in the electromagnetic variables and provides a fixed switching frequency for the voltage source inverter that feeds the motor. Simulation analysis has been done to demonstrate the effectiveness of the proposed scheme.
