Simulation of Vector Control System of Permanent Magnet Synchronous Motor

The article analysed and studied the structure performance and mathematical model of the permanent magnet synchronous motor, and it further researched the principle of vector control technology and the SVPWM algorithm on this basis. A closed-loop simulation model of permanent magnet synchronous motor speed/current was built. The waveform of the simulation result is consistent with the theoretical analysis, which verifies the effectiveness of the simulation experiment platform and mathematical model. It also verifies the superiority of the id=0 control algorithm and vector control. A theory for the research and design of the permanent magnet synchronous motor vector control system basis is provided. (paper)
