Fault detection filtering for continuous-time singular systems under a dynamic event-triggered mechanism

Abstract

<p style='text-indent:20px;'>This paper focuses on the problem of fault detection filtering (FDF) for continuous-time singular systems via a dynamic event-triggered mechanism. Firstly, in order to reduce signal transmission and save network resources, a dynamic event-triggered mechanism is adopted. Compared with the static mechanism, the proposed method is more effective on reducing network transmission pressure since a dynamic variable is introduced. Secondly, a novel criterion is derived to guarantee the admissibility of the residual system with a certain <inline-formula><tex-math id="M1">\begin{document}$ \mathcal{H}_\infty $\end{document}</tex-math></inline-formula> performance. According to the derived conditions, a new method is given to codesign the desired filter and the event-triggered parameters. Finally, an example is employed to illustrate the validity of the proposed approach.</p>
