摘要:
为了确保无线网络控制系统运行的可靠性,该文针对由无线传感器网络组成的网络控制系统,设计了基于离散切换系统的故障观测器。假定其可能发生故障,对其进行故障检测研究。通过研究无线传感器网络数据的传输特性,构建了增广故障观测器。将该观测器等效为离散切换系统。利用李雅普诺夫稳定性理论将观测器稳定条件归结为1个线性矩阵不等式,给出了稳定性证明。该观测器能在1s内跟踪上原系统的状态。当系统发生故障时,观测器残差能够迅速发生跳变,从而检测故障。仿真示例验证了该文方法的有效性。
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.
