Abstract
In this paper, a vector-controlled five-phase E-core flux-switching permanent-magnet (FSPM) machine drive system is proposed, in which three different control methods are applied, namely, current-hysteresis control, space-vector pulsewidth modulation (SVPWM) method-1 using only large basic vectors, and SVPWM method-2 using large and medium basic vectors in each section, respectively. The operation principle and simulated results are given. Then, a DSP-based driving system employing an E-core five-phase FSPM prototyped machine is set up to verify the proposed control method. Finally, a comparison among the three control methods is discussed, and it reveals that the SVPWM method-2 shows the best performance both in phase current waveform and in output torque.
