含未知输入观测器的广义系统故障诊断

基于未知输入观测器设计和故障诊断的概念，讨论含未知输入的Lipschitz条件下非线性广义系统传感器故障诊断问题。在非线性广义系统中，通过引入传感器的故障信号，重新构造非线性广义系统，设计基于未知输入观测器，在满足Lipschitz条件下，实现了传感器故障的检测与分离。给出数值仿真算例验证该算法的有效性。

Fault Diagnosis for Singular Systems with Unknown Input of Observers

Based on the design of unknown input observers and the concept of fault diagnosis,this paper considers the problem of sensor fault diagnosis for nonlinear singular systems with unknown input observers of Lipschitz.It has reconstructed a nonlinear singular systems with the sensor fault signal,designed a observer based on unknown input,and realized the sensor fault detection and separation under the Lipschitz.A numerical example is presented to illustrate the algorithmic validity.
