Taking 5-phase permanent magnet synchronous motor as the research object, the space vector pulse width modulation control algorithm is analyzed and researched, and a 5-phase permanent magnet synchronous motor control system is established. The feasibility of space vector pulse width modulation algorithm is verified in MATLAB.
