中文摘要：
研究了一类具有不确定时滞的无线网络控制系统的故障检测的问题。由于时滞是不确定的,可以通过增广向量法将系统建模为马尔科夫跳变系统。在此基础上,设计了观测滤波器,满足了滤波器在没有扰动的情况下均方指数稳定,在有扰动时,满足一定的H∞鲁棒性能。当系统发生故障时,故障检测系统立即检测出故障。所得结果通过仿真示例得到了验证。
英文摘要：
This paper addressed the problem of the fault detection for a class of wireless networked control systems with uncertain time delay.Since the delay is uncertain,the system can be modeled as a Markov jump systems through augmented vector method.On the basis of the model above,this paper designed a observer-based filter,by choosing the appropriate filter gain,the filter was mean square convergent if there was no disturbance,and the filter would satisfy certain H∞ robust performance if disturbance exists.When a fault occurs,the fault detection system would detect the fault rapidly.Simulation examples verify all results.
