摘要
基于化工中反应釜的温度变化给出了一类连续时间分段线性系统的观测器设计过程。针对系统使用了Luenberger型观测器,导出了观测误差动态全局同步系统可观测的充分条件,并利用动态系统的残差进行分析达到对原系统进行故障检测的目的,最后通过数值仿真证明了故障检测的可行性。
Based on the temperature variation of reaction kettle in chemical industry,the observer design process for a class of continuous time piecewise linear systems is presented in this paper.Luenberger observer is used for the system,and the sufficient conditions for the observability of the dynamic global synchronization system with observation errors are derived.The residual of the dynamic system is used to analyze the fault detection of the original system.Finally,the feasibility of fault detection is proved by numerical simulation.
