Study and Simulation of AC Motor Vector Control Based on SVPWM

This paper mainly study the Space Vector Pulse Width Modulation (SVPWM) algorithm of AC motor control system, Vector control strategy of the SVPWM voltage source inverter fed AC motor studied. In order to testify the correctness of the control strategy, simulation method is proposed to modify the motor speed and realize a simple and high performance speed control system. This system has been implemented on dynamic simulated tool simulation of MATLAB software in AC motor. Results show that the method gives satisfying rotor speed in the whole speed range and can improve the control precision.
