Simulation study on the vector control system of asynchronous motor

Aim To provide theoretical basis and system parameters for the engineering design of the vector control system of asynchronous motor.Methods According to the mathematical model of the three-phase asynchronous motor in the coordinate system,the rotor field-oriented vector control principle is use to build the vector control simulation model of asynchronous motor in MATLAB/SIMULINK simulation platform.Results The simulation results show that the vector control system can not only quickly response to the variation of the load torque but also have good dynamic and static performance.Conclusion Asynchronous motor vector control system features simple structure,high control precision,so it can satisfy the high performance requirements of AC speed regulation in practical engineering.
