Modeling and simulation of vector control and variable-frequency regulating speed system of asynchronous motor based on Matlab

Vector control is regard as a major control method on high performance induction motor speed control system. The paper describes the composition of vector control system and control theory, built a simulation model of vector control system based on Matlab/Simulink software, analysis of mutations in a given speed of operation of the motor, and gives the speed and current simulation waveforms. The results show that the model is correct, reasonable and effective. Results show that it has good dynamic and static performance, and it realizes the decoupling control system. It can help us better design and debug the motor control system.
