摘　　要：高速磁悬浮列车用长定子直线同步电机工作在双端供电模式时,是多变量、非线性、强耦合系统。传统的线性控制方法对参数摄动较为敏感,因此该文分析了参数摄动对电流环控制性能的影响并提出一种基于积分滑模的电流控制策略。该策略将状态变量的积分项引入到滑模面中,避免了高频噪声的干扰,并改进了指数趋近律以削弱抖振,使得电流的动态跟随性能和抗参数摄动性能都得到改善。硬件在环实验验证了该策略与传统线性控制策略相比,可提高磁悬浮列车在定子段换步过程中的电流跟随性能,并且对电机参数摄动具有较强的鲁棒性。When the long-stator linear synchronous motor for high-speed maglev train works in the double feed mode,it is a multi-variable,nonlinear,and strongly coupled system.The traditional linear control method is more sensitive to parameter perturbation,so this paper analyzes the influence of parameter perturbation on current loop control performance and proposes a current control strategy based on integral sliding mode.This strategy introduces the integral term of the state variables into the sliding mode surface,avoids the interference of high-frequency noise,and improves the exponential reaching law to weaken chattering,so that the current dynamic following performance and parameter perturbation resistance are improved.Hardware-in-the-loop(HIL)experiments verify that compared with the traditional linear control strategy,this strategy can improve the current following performance of the maglev train in the step change process of the stator section and has strong robustness to the perturbation of motor parameters.
