Space Vector Flux Weakening Control of PMSM Drivers

Abstract

Permanent Magnet Synchronous Motor is widely used in industry, medicine and other fields. Based on the mathematical model of permanent magnet synchronous motor (PMSM), a system of modeling and simulation of PMSM was constructed by MATLAB/Simulink, and two PI controllers were used in the speed loop and current loop. This paper presents the principle of pulse width modulation based on voltage space vector, and the simulation model of PMSM control system based on SVPWM is built in MATLAB/Simulink. In the end, some experiments are carried out to the whole system, and it proves that the system is of good performance both in steady and dynamic state.
