基于模糊模型的无线网络控制系统故障检测

考虑控制器与被控对象之间采用无线传输，且被控对象为非线性模型的一类网络控制系统，对其进行故障检测。首先基于T-S模糊模型将对象线性化，利用模糊主导子系统规则，设计了模糊观测器，并得出了观测器误差方程。然后将误差方程等效为与无线传输跳数相关的离散切换系统，并证明了误差系统的稳定性。最后，通过仿真实例验证了所提方法的有效性。

Fault detection of wireless networked control systems based on fuzzy model

Considering a class of networked control systems using wireless transmission between the controller and the controlled object with nonlinear models,the fault detection is carried out.Firstly,based on a T-S fuzzy model,the object is linearized.The fuzzy observer is designed and the error equation of the observer is given by using the fuzzy dominant subsystem rule.Secondly,the error equation is equivalent to the discrete switched system related to the hop count of the wireless transmission,and the stability o...
