Aiming at the characteristic of permanent magnet synchronous motor direct torque control, the paper puts forward a kind of control strategy combining matrix convener technology with permanent magnet synchronous motor direct torque control technology.This strategy has the advantages of matrix convefler and direct torque control, which can control effectively of the permanent magnet synchronous motor.The system model simulation experiment was catTied out by Using MATALAB/SIMULINK tool box.The simulation results show that the system has good dynamic and static performance and transmission performance, and it can realize two—way flow of energy.
