Performance Improvement of Permanent Magnet Synchronous Motor fed by Direct Matrix Converter by using Second-Order Sliding Mode Control

Abstract

The main object of this study is the design and the application of second order sliding mode controllers based on the super twisting algorithm for the vector control of synchronous permanent magnet motor fed by direct matrix converter, in order to get high performance in terms of specification required of dynamic behaviors. In this framework, thanks to its success with regard to its reduced conduction losses, the space vector modulation technique was chosen as a switching algorithm to control the matrix converter. On the other hand, a passive filter with a damping resistor has been inserted at the input of the matrix converter to prevent the injection of harmonics by the drive system into the grid. Finally, the effectiveness and feasibility of the proposed control approach for the considered drive system was examined and verified by simulation.
