| 摘 要： | 以磁悬浮列车单模块悬浮系统为对象,考虑系统存在的输入时滞,建立了时滞悬浮系统的数学模型,基于状态反馈和线性矩阵不等式处理方法,设计了在执行器发生故障情况下的鲁棒H∞容错控制器,在此基础上,针对不同执行器故障模式,对悬浮间隙的变化情况进行了仿真。仿真结果表明所设计的控制器在执行器故障条件下能够使磁悬浮列车稳定悬浮与运行。

| Abstract: | Taking into account of the input time-delay,mathematical model of the suspension system was established for single suspension module of maglev train.Based on state feedback and LMI approaches,robust H fault tolerant controller was designed under the case of actuator failures,furthermore,the gap variation in case of different actuator failures was simulated.Simulation results showed that the designed fault tolerant controller could make the maglev train suspend and run steadily with actuator failures. |
