Model predictive direct torque control of matrix converter-fed PMSM drives using branch and bound algorithm for torque ripple minimization

摘要

A Model Predictive -Direct Torque Control (MP-DTC) technique is proposed for Matrix Converter (MC)-based Permanent Magnet Synchronous Motor (PMSM) drive system, which reduces the torque ripples, does not need the duty cycle calculation, and ensures the fixed switching frequency. The predictive model of PMSM and MC is realized by means of State model. Then, the advanced MC-fed model predictive DTC algorithm is implemented based on cost function evaluation. The simulation results exhibit remarkable torque ripple reduction with the help of Model Predictive Control (MPC). As a result, the proposed strategy is proved to be effective in minimizing the torque ripples for MC-based PMSM drives.
