Analysis, simulation and experimental strategies of 5-phase permanent magnet motor control

This paper presents a study of control strategies for 5-phase permanent magnet synchronous motors (PMSMs) supplied by five-leg voltage source inverter. Based on the vectorial decomposition multi-phase machine, fictitious machines, magnetically decoupled, allow more adequate control. In this paper, our focuses vector machine using linear proportional-integral-derivative (PID) current regulator in cases sinusoidal and trapezoidal back-electromotive force (EMF) waveforms. order to determine currents' references, two are adopted. First one aims minimize copper losses under constant torque, while second targets increase torque given losses. These techniques tested variable speed strategy based proportional-integral (PI) experimentally validated.
