研究了五相感应电动机的有限控制集模型预测控制（FCS-MPC）。具体而言，性能方面的不同的选择逆变器开关状态进行了研究。电机在转子磁通定向下运行，并且磁通/转矩产生（d-q）和非磁通/转矩产生（x-y）电流都包括在二次成本函数中。性能评估的基础上的主平面，副平面，和相（平均）电流纹波，在整个逆变器的线性操作区域下恒定的磁通量-转矩操作。在代价函数中增加了二次平面电流涟漪加权因子，并评估了其对所有研究方案的影响。从而建立了最佳开关状态集和加权因子选择的准则。所有的考虑都伴随着仿真和实验结果，这是进一步比较的稳态和瞬态性能的比例积分脉宽调制（PI-PWM）为基础的电流控制方案。虽然FCS-MPC获得了更好的瞬态性能，但PI-PWM控制的稳态性能始终是上级。有人认为，这是不可避免的，在多相驱动器一般，由于存在的nonflux/转矩产生电流分量。
This paper presents an investigation of the finite-control-set model predictive control (FCS-MPC) of a five-phase induction motor drive. Specifically, performance with regard to different selections of inverter switching states is investigated. The motor is operated under rotor flux orientation, and both flux/torque producing (d-q) and nonflux/torque producing (x-y) currents are included into the quadratic cost function. The performance is evaluated on the basis of the primary plane, secondary plane, and phase (average) current ripples, across the full inverter's linear operating region under constant flux-torque operation. A secondary plane current ripple weighting factor is added in the cost function, and its impact on all the studied schemes is evaluated. Guidelines for the best switching state set and weighting factor selections are thus established. All the considerations are accompanied with both simulation and experimental results, which are further compared with the steady-state and transient performance of a proportional-integral pulsewidth modulation (PI-PWM)-based current control scheme. While a better transient performance is obtained with FCS-MPC, steady-state performance is always superior with PI-PWM control. It is argued that this is inevitable in multiphase drives in general, due to the existence of nonflux/torque producing current components.
