MC-PMSM Control System Based on Improved M2PC Control Method
Aiming at the problems existing in the traditional model predictive control(MPC)method and modulation model predictive control(M2PC)method,we put forward an improved M2PC method and apply it to the matrix converter(MC)-permanent magnet synchronous motor(PMSM)system control.Firstly,the topology of MC-PMSM is given,and the existing problems of MC-PMSM control system based on traditional MPC and M2PC methods are analyzed.Then,a solution based on the improved M2PC method is proposed,which can not only fix the switching frequency,but also re-duce the amount of calculation and improve the waveform quality.Finally,the MC-PMSM system is simulated on the RTDS platform using the improved M2PC method,and compared with the traditional MPC and M2PC methods.The re-sults show that the control performance of the proposed improved M2PC method is superior to the traditional MPC and M2PC methods.
