针对采用三相电压源换流器（VSC）的互耦开关磁阻电机（MCSRMs），提出了一种滑模电流控制器（SMC）。本文首先以三相电压源换流器为例，建立了MCSRMs的广义状态空间模型。比较了不对称桥式变换器和三相电压源型变换器的开关频率。然后，滑模电流控制器的设计，以实现恒定的开关频率和较低的采样率，使用三相VSC。对滑模控制器进行了稳定性分析，保证了控制器的稳定性。最后，SMC的有效性进行了验证，通过仿真研究与三相，正弦激励12/8 MCSRM在很宽的速度范围内。与滞环电流控制相比，SMC在转矩脉动、转矩均方根跟踪误差（RMSE）和电流RMSE方面表现出相当的性能，同时实现恒定的开关频率和低得多的采样率。
In this paper, a sliding mode current controller (SMC) is proposed for mutually coupled switched reluctance machines (MCSRMs) using a three-phase voltage source converter (VSC). A generalized state-space model of MCSRMs is first presented using a three-phase voltage source converter. Asymmetric bridge converters and three-phase voltage source converter are compared in terms of switching frequency. A sliding mode current controller is then designed to achieve constant switching frequency and lower sampling rate using a three-phase VSC. The stability analysis of the sliding controller is given to ensure the stability of the controller. Finally, the effectiveness of SMC is verified through simulation studies with a three-phase, sinusoidal excitation 12/8 MCSRM over a wide speed range. Compared to the hysteresis current control, SMC demonstrates a comparable performance in terms of torque ripples, torque root-mean-square tracking errors (RMSE) and current RMSE while achieving a constant switching frequency and much lower sampling rate.
