基于概率密度函数的时滞依赖故障检测与诊断
Fault detection and diagnosis based on PDF and time-delay
摘要
Abstract
In this paper, a method of fault detection and diagnosis based on Probability Density Function(PDF)is pro-posed for stochastic distributed systems with time-delay.The residual of the PDF information is established firstly,then it designs fault detection observer and fault estimator based on the linear matrix inequality utilizing the theory of fault detec-tion and diagnosis,and passes through the stability analysis,realizes fault detection and estimation of the system.Finally, the numerical simulation shows the effectiveness of the method.关键词
