As for networked control systems under deception attacks, a co-design strategy of event-triggered mechanism and secure controller is proposed. Firstly, a discrete-time event-triggered mechanism is introduced, which overcomes limits of continuous-time event-triggered mechanism requiring dedicated hardware and complex Zeno-avoidance computation. Secondly, a time-delay closed-loop system model is built, which integrates parameters of deception attacks, event-triggered mechanism, network-induced delays and external disturbances in a unified framework. Then, sufficient conditions for asymptotic stability of the attacked event-triggered systems are derived, and the co-design scheme of event-triggered mechanism and secure controller is presented. Finally, simulation confirms the proposed methods.

Key words: networked control system, deception attack, event-triggered mechanism, asymptotic stability, co-design
