Modeling and simulation of asynchronous motor control system based on MATLAB/Simulink

In this paper,based on the means of asynchronous motor’s rotor flux-oriented vector control,and the shortcomings that rotor flux is influenced by motor parameters in magnetic linkage closed loop,this article adopts vector control scheme of magnetic flux opended loop.By modular thought,the functional modules of the opening magnetic flux loop of vector control system is modeled in MATLAB/Simulink.Through the organic integration of each functional modules,a simulation model of vector control system is modeled.The results show that the system has a good dynamic performance and the anti-interference ability,so the feasibility and effectiveness of the modeling method is validated.The results also provides a theoretical foundation for design and debug of actual motor control system.
