摘要: 讨论了一类非线性系统执行器故障的诊断问题.首先应用已有的状态和输出变换, 将一类非线性系统转化为两个低维子系统,然后利用滑模观测器设计理论和等价控制的概念 重构执行器故障.Abstract: This paper considers the problem of actuator fault detection for a class of nonlinear systems. A nonlinear systems can be decomposed using some state and output transformation method, and then actuator fault can be directly reconstructed by the sliding mode observer theory and the concept of the equivalence control.
