针对互联型开关磁阻电机(MCSRM)提出了一种积分滑模电流控制器(SMC)，该控制器采用不对称桥式变流器，以实现恒定开关频率和较低的采样率。建立了广义状态空间模型，设计了滑模控制器，并对闭环系统进行了稳定性分析。通过对三相正弦励磁12/8MCSRM在宽转速范围内的仿真研究，验证了SMC的有效性。与滞环电流控制相比，基于SMC的设计方法在实现恒定开关频率和较低采样率的同时，在电流纹波、电流和转矩的均方根误差方面表现出与之相当的响应。
In this paper, an integral sliding mode current controller (SMC)is proposed for mutually coupled switched reluctance motors (MCSRM)using asymmetric bridge converters aiming to achieve constant switching frequency and lower sampling rate. A generalized state-space model is built and then the design of a sliding mode controller along with the stability analysis of the closed-loop system are presented. The effectiveness of SMC is verified using simulation studies with a three-phase, sinusoidal excitation 12/8 MCSRM over a wide speed range. Compared to the hysteresis current control, the proposed SMC-based design approach demonstrates a comparable response in terms of currents ripples, the root-mean-square error of current and torque while achieving a constant switching frequency and lower sampling rate.
