摘　　要：针对摆式列车倾摆系统参数和作动器故障的不确定性,采用基于解析冗余的主动容错方法研究了作动器发生非完全失效故障情况下的容错控制.建立了作动器故障模型,采用模型参考自适应控制算法设计了基于状态反馈的自适应故障补偿控制器,实现了系统故障后作动器驱动力的重组.设计的控制率能够保证系统在执行器非完全失效故障时闭环系统稳定,仿真示例表明了所提出方法的有效性.An active fault-tolerant control method is presented for tilting control system of tilting train with partial actuation faults.Based on analytical redundancy,a model reference adaptive control algorithm is designed for the system with uncertainty of parameters and actuation faults.Actuation fault model is built firstly.Subsequently,an adaptive actuator failure compensation controller based on the state feedback is designed.Actuator reconfiguration is performed in the post-fault system.The proposed control law can guarantee that the closed-loop system with partial actuation faults is stable.Simulation results demonstrate the effectiveness of the proposed method.
