针对电压源逆变器（VSI）驱动的永磁同步电机（PMSM）系统，提出了一种基于滑模扩张状态观测器（SMESO）的自适应扰动补偿有限控制集最优控制（FCS-OC）策略。为了提高有限控制集最优控制策略的鲁棒性，提出了一种SMESO估计输出效应扰动。将估计值反馈给有限控制集最优控制器，实现扰动补偿。理论分析表明，所设计的SMESO能在有限时间内收敛。仿真结果表明，所提出的自适应扰动补偿FCS-OC具有更好的动态响应行为的干扰存在。
Based on sliding mode extended state observer (SMESO) technique, an adaptive disturbance compensation finite control set optimal control (FCS-OC) strategy is proposed for permanent magnet synchronous motor (PMSM) system driven by voltage source inverter (VSI). So as to improve robustness of finite control set optimal control strategy, a SMESO is proposed to estimate the output-effect disturbance. The estimated value is fed back to finite control set optimal controller for implementing disturbance compensation. It is indicated through theoretical analysis that the designed SMESO could converge in finite time. The simulation results illustrate that the proposed adaptive disturbance compensation FCS-OC possesses better dynamical response behavior in the presence of disturbance.
