Abstract

To reduce the switching frequency and enhance the parameter robustness of open-winding permanent magnet synchronous motors (OW-PMSMs) with isolated DC power sources, a novel dual-vector model predictive current control (DV-MPCC) method with sliding mode observer (SMO) is proposed. First, the DV-MPCC is presented in OW-PMSM system with isolated DC power sources, which can reduce the switching frequency of OW-PMSM system by 50% compared with the conventional deadbeat predictive current control (DPCC) method. Second, a SMO is innovatively applied to isolated OW-PMSM, which can estimate the disturbances caused by stator inductance, stator resistance, and flux linkage mismatch of OW-PMSM with isolated DC power sources. The stability of the observer is analyzed by the Lyapunov function. Then, combine the SMO and DV-MPCC, the disturbance observed by SMO is used to correct the reference voltage calculated by DV-MPCC, so as to obtain a more optimized switching state and duty cycle. To verify the proposed method, the conventional MPCC the DV-MPCC and the DV-MPCC+SMO methods are compared by simulations and experiments.

为了降低带隔离直流电源的开绕组永磁同步电机（OW-PMSM）的开关频率并增强其参数鲁棒性，本文提出了一种带有滑模观测器（SMO）的新型双矢量模型预测电流控制（DV-MPCC）方法。首先，在具有隔离直流电源的 OW-PMSM 系统中提出了 DV-MPCC，与传统的死区预测电流控制（DPCC）方法相比，该方法可将 OW-PMSM 系统的开关频率降低 50%。其次，创新性地将 SMO 应用于带隔离直流电源的 OW-PMSM 系统，该观测器可估算带隔离直流电源的 OW-PMSM 系统的定子电感、定子电阻和磁通联结失配引起的干扰。利用 Lyapunov 函数分析了观测器的稳定性。然后，结合 SMO 和 DV-MPCC，利用 SMO 观察到的扰动来修正 DV-MPCC 计算出的参考电压，从而获得更优化的开关状态和占空比。为了验证所提出的方法，我们通过仿真和实验对传统 MPCC 方法、DV-MPCC 方法和 DV-MPCC+SMO 方法进行了比较。
