Fault Detection for Wireless Sensor Networked Control Systems
摘要
Abstract
In order to ensure the reliability of wireless networked control systems, a fault observer based on discrete switched systems is designed focusing on networked control systems composed of wireless sensor networks. The wireless networked control system is assumed to be fault and detected. The augmented fault observer is constructed by studying the transmission characteristics of the data of wireless sensor networks. The observer is equivalent to a discrete switched system. The stability condition of the observer is translated into a linear matrix inequality based on the Lyapunov stability theory,and the stability of the system is proved. The observer can keep track of the state of the original system in one second. When a fault occurs,the observer residue can change rapidly to detect the fault. The simulation example demonstrates the effectiveness of the proposed method.关键词
