研究一类非线性系统中故障的检测.由于此类的故障分布函数不仅仅只依赖系统中的输入与输出向量,同时也依赖于不可测的状态,所以增加了故障估计中的复杂性.在拟单边Lipschitz的条件下建立了故障检测观测器,最后证明观测器的渐进稳定性以及故障估计误差的一致有界性.“,”In this paper,the detection of faults in a class of nonlinear systems are studied.Since such a fault distribution function depends not only on the inputs and outputs of the system but aslo on unmeasured states,it causes additional complexity in fault estimation.Under the Quasi-one-sided Lipschitz condition,a fault detection observer and adaptive diagnosis observer are proposed.The asymptotically stability of the adaptive observer and the uniform boundedness of the fault estimation error vector are proved by Lyapunov theorem.
