Research on Speed Control System of AC Asynchronous Motor

Abstract

With the continuous development of modern industry, the engineering practice is becoming more and more complicated. in view of the poor speed regulation performance of AC motor, such as slow response speed and weak anti-interference ability, based on the modular design idea, based on the theory of constant voltage-frequency ratio control and vector control, starting with the mathematical model of asynchronous motor, the simulation experiments are completed through MATLAB simulation software, and the components of the simulation model are analyzed step by step. The corresponding simulation waveforms are obtained from the two models. The simulation results show that the vector control method has better dynamic and static performance, especially in the case of sudden load.
