Output-based decentralised event-triggered dissipative control of NCSs under aperiodic DoS attacks

Abstract

This paper studies output-based decentralised event-triggered dissipative control of NCSs under aperiodic DoS attacks. Firstly, to save constrained system resources such as network bandwidth, using information on aperiodic DoS attacks, an output-based decentralised resilient event-triggered mechanism (ETM) is introduced. Secondly, a switched system model is built, which characterises effects of aperiodic DoS attacks, decentralised resilient ETM and disturbances in a unified framework. Thirdly, sufficient conditions are derived such that the system is exponentially stable and strictly $(\mathcal{G}$, $\mathcal{H}$, $\mathcal{I})$-dissipative, which establish quantitative relationships among aperiodic DoS attacks, decentralised resilient ETM, disturbances and system performance. Further, co-design conditions are presented to compute parameters of switched dynamic output feedback controller and decentralised resilient ETM simultaneously. Finally, examples illustrate effectiveness of the proposed method.
