Research on Vector Control Strategy and SVPWM Algorithms Based on Five-phase PMSM

The five-phase permanent magnet synchronous motor (PMSM) has been widely used in electric vehicles and other applications due to its reliable performance, rich control scheme and other advantages. On the base of motor mathematic model, an improved vector control scheme which is designed with the motor characteristics is proposed to reduce the harmonic loss. Theoretical analysis and simulation of SVPWM algorithms is given to compare the harmonic content and utility of the proposed vector control scheme has been verified by simulation.
