To deal with the single-phase open-circuited fault, an enhanced fault-tolerant model predictive current control with continued modulation is proposed in this article. This method includes reconstructing the postfault vector distribution and adopting a multistep vector selection method. In the reconstruction procedure, the transition vectors are generating to realize standard pulsewidth modulation waveforms. Then, the unreachable area can be filled by creating new synthetic vectors. Finally, the vectors with oversized amplitudes are optimized by using null vectors. In order to cover the full modulation area, a multistep vector selection method is used to determine the phase angle and amplitude of the optimal vector. The phase angle can be determined by defining two cost functions and adopting duty cycle modulation technology. The amplitude of the optimal vector can be optimized by utilizing the duty cycle modulation technology again. The oscillation, due to the back electromotive force, is compensated in each step. A thorough experimental evaluation has been conducted to confirm the effectiveness and superiority of the proposed fault-tolerant method.

具有持续调制的五相永磁电机的增强容错模型预测电流控制

针对单相开路故障，本文提出了一种具有连续调制的增强容错模型预测电流控制。该方法包括重构故障后矢量分布和采用多步矢量选择方法。在重建过程中，生成过渡向量以实现标准的脉宽调制波形。然后，可以通过创建新的合成向量来填充无法到达的区域。最后，使用空向量优化幅度过大的向量。为了覆盖整个调制区域，采用多步矢量选择方法来确定最佳矢量的相位角和幅度。相位角可以通过定义两个成本函数并采用占空比调制技术来确定。再次利用占空比调制技术可以优化最优矢量的幅度。由于反电动势而产生的振荡在每一步都得到补偿。已经进行了彻底的实验评估，以确认所提出的容错方法的有效性和优越性。
