Simulation Analysis of AC Motor Frequency Converter Based on Vector Control

The vector control frequency conversion speed regulation technology has its profound significance in today's higher and higher requirements for the quality of AC speed regulation. In this paper, a variable frequency speed regulation system of AC motor is designed. The vector control method based on the rotor flux linkage is adopted to form a circular rotating magnetic field inside the motor, and the purpose of optimizing the speed regulation accuracy is finally achieved. This paper focuses on the design and control method of the system, and then uses Matlab/Simulink to establish the simulation model of the system. The simulation analysis shows that the system has fast dynamic response speed and good static stability, which fully verifies the feasibility of the system.
