Vector Control of Rotating Platform Azimuth Permanent Magnet Synchronous Motor

Permanent magnet synchronous motors are increasingly used in various power levels, and the control of permanent magnet synchronous motors is a key technology in the application of synchronous motors. The structural characteristics of permanent magnet synchronous motors make vector control systems have great advantages. This paper introduces the vector control strategy of permanent magnet synchronous motor based on rotor magnetic field orientation, determines PI parameters, designs current loop regulators and speed loop regulators, analyzes the SVPWM method used in vector control, and builds a module on simulation software for the simulation of permanent magnet synchronous motor. Through detailed calculation of the PI parameters of the current loop and voltage loop of the dual closed-loop control, appropriate adjustments were made based on the ideal output waveform during the simulation process, and simulation verification was conducted on the simulation software.
