For a semi-controlled open-winding permanent magnet synchronous motor, to improve the steady-state control performance of the traditional predictive control system and to concurrently lessen the computation burden, a novel model predictive current control strategy is proposed in this paper. First, to achieve simultaneous control of the d-axis current, q-axis current, and current error-based cost functions. Then, to further reduce the calculation burden and complexity of the prediction algorithm, the predicted voltage of the converter is used as the reference voltage. In addition, the judgment of the sector where the reference voltage is located, and the selection method of the voltage vector are also given. Finally, the effectiveness of the proposed prediction method is tested by the simulation and experimental results.

针对半开环永磁同步电动机，为提高传统预测控制系统的稳态控制性能，同时减轻计算负担，提出了一种新型的模型预测电流控制策略。首先，要实现d轴电流q的同时控制轴当前和基于误差的当前成本函数。然后，为了进一步减轻预测算法的计算负担和复杂度，将转换器的预测电压用作参考电压。另外，还给出了参考电压所在扇区的判断以及电压矢量的选择方法。最后，通过仿真和实验结果验证了所提预测方法的有效性。
