Simulation Study of Permanent Magnet Synchronous Motors Energy Feedback Control System

Abstract

Combined with the brake working principle of Permanent magnet synchronous motors, the three-phase PWM rectifier mathematical model and Simulink simulation model are set up. On this basis, according to the design requirements of energy feedback system, the voltage current double-loop control is applied in this system. The space voltage vector tracking is achieved by the use of space voltage vector PWM algorithm. The system modeling and simulation study is conducted in the MATLAB simulation environment, and the correctness of the proposed program is verified, which provides the corresponding theoretical basis for the future product design.
