| 摘 要： | 提出了一种利用未知输入观测吕（ＵＩＯ）对摆式列车倾摆控制系统执行机构进行故障检测的方法。该方法是干扰解耦原理的一个应用，通过一个全阶未知输入观测器使残差对未知输入不敏感，而对故障敏感，通过一个简单阈值逻辑来检测故障，通过计算机仿真证明了该方法的有效性。

| Abstract: | This paper proposes a UIO based fault detection approach to the actuator of tilting control system of tilting trains. The approach is the use of the disturbance de coupling principle, in which the residual is designed to be insensitive to unknown disturbances, whilst sensitive to faults. This is done by using a full order unknown input observer (UIO). The residual can be used to detect faults according to a simple threshold logic. Simulation results show the efficiency of this method. WT5HZ] |
