Security control for adaptive event-triggered networked control systems under deception attacks

Abstract

This paper addresses the problem of the security control for adaptive event-triggered networked control systems under deception attacks. For the considered systems, data transmission is based on the network. To alleviate the network bandwidth pressure, an adaptive event-triggered mechanism, the triggered condition of which can be regulated adaptively according to the system states, is employed. By considering the effects of deception attacks, a novel mathematical model is established for networked control systems under discussion. Then by implementing Lyapunov stability theory, the co-design of controller gain and the parameter of adaptive event-triggered mechanism is achieved. Finally, a simulated example is offered to illustrate the feasibility of the proposed method.
