为进一步提高永磁同步电机自抗扰控制器(ADRC)的调速控制性能，简化控制器参数整定的复杂程度，提出了一种复合ADRC控制策略。首先，速度环采用模糊参数整定的滑模自抗扰控制器，并分析了主要参数的整定方法。其次，设计了滑模转矩观测器，来估计实时的负载转矩。最后，设计电流环，采用有限集模型预测控制(FCS-MPC)，对三相两电平电压源型逆变器的8种开关序列遍历寻优，并抑制转矩的脉动。仿真结果表明：该复合控制策略能有效提高永磁同步电机ADRC的控制性能，增强系统的抗扰动能力以及鲁棒性，控制性能优于传统的ADRC控制和PI控制。

In order to further improve the speed control performance of active disturbance rejection controller (ADRC) for permanent magnet synchronous motor (PMSM), and simplify the complexity of controller parameter setting, a compound ADRC control strategy is proposed. Firstly, the sliding mode ADRC with fuzzy parameter tuning is used in the velocity loop, and the tuning methods of the main parameters is analyzed. Secondly, a sliding mode torque observer is designed to estimate the real-time load torque. Finally, the current loop is designed, and the finite set model predictive control (FCS-MPC) is used to optimize 8 kinds of switching sequences of three-phase two-level voltage source inverter and suppress torque pulsation. The simulation results show that the composite control strategy can effectively improve the control performance of the permanent magnet synchronous motor ADRC, enhance the anti-disturbance ability and robustness of the system, and the control performance is better than the traditional ADRC control and PI control.
