Simulation Study of AC Motor Speed Sensorless Vector Control System Based on SVPWM

摘要：

The paper applies the Space Vector Pulse Width Modulation (SVPWM) algorithm to speed sensorless vector control system according to the theory of Space Vector Pulse Width Modulation, so as to enhance the stability and the performance of speed sensorless drives. The vector control strategy of the SVPWM voltage source inverter fed induction motor is studied. To testify the correctness and feasibility of the scheme, the simulation method is proposed to estimate the motor speed and realize a simple and high performance speed sensorless system. This system has been implemented on dynamic simulated tool SIMULINK of MATLAB software in AC motor. The simulation results show that the method gives satisfying estimation of stator flux and rotor speed in the whole speed range and can improve the control precision.
