The Research of Direct Torque Control of Five-Phase Permanent Magnet Synchronous Motor

The most important part of the direct toque control for five-phase PMSM is to select the appropriate voltage vectors. This paper develops two methods for this. First the PI control method is used to decide the reference voltage vector and second the way for selecting proper voltage vectors to synthesize the reference voltage vector in order to minimize the effection of harmonics current is gived. Simulations results verify its validity.
