In order to reduce harmonic pollution in the AC adjusted speed system and realize a high transmission performance for asynchronism motor, a control strategy based on matrix converter of asynchronous motor vector control system is proposed. It realize space vector modulation of matrix converter and flux-oriented vector control method of asynchronism motor, and add voltage compensation module with corresponding improvement strategies to SVPWM control system of asynchronous motor with corresponding improvement strategies. The simulation of MATLAB suggests control strategy has good performance of speed adjustment and improves quality of input power.
