摘　　要：高速磁浮列车在同步旋转坐标系下dq轴电流存在耦合,当工作在双端供电模式时,电流耦合严重,影响磁浮列车的稳定运行。传统的解耦控制策略对参数敏感,因此该文提出一种基于自抗扰的电流解耦控制策略。该策略把电流耦合以及电感参数变化引起的电压误差视为系统扰动,通过扩张状态观测器来观测,对扰动进行前馈补偿,从而抵消扰动对系统的影响。仿真和硬件在环实验验证了该策略对电感参数变化具有较强的鲁棒性,能实现电流解耦,可降低磁浮列车在定子段换步过程中的电流波动,提高了系统动态性能。The dq current of the high-speed maglev is coupled in synchronous-frame,when working in the double feed mode,the current coupling is severe,which affects the stable operation of the maglev train.The traditional decoupling control strategy is sensitive to parameters,so this paper proposes a current decoupling strategy based on active disturbance rejection control(ADRC).This strategy considers the voltage error caused by current coupling and changes of inductance parameter as system disturbance,then observes disturbances through the extended state observer,and feeds forward the disturbance to compensate the influence of the disturbance on the system.Simulation and hardware-in-the-loop(HIL)experiments demonstrate that the strategy has strong robustness to parameters and it can achieve current decoupling,reduce the current fluctuation of the maglev train during the stator section changeover process,improve system dynamic performance.
