Dynamic event-triggered L∞ control for networked control systems under deception attacks: a switching method

Abstract Based on the event-triggered scheme (ETS), the L ∞ control problem is considered for networked control systems subject to stochastic deception attacks. A novel dynamic switching ETS is proposed to reduce the number of transmitted signals. A stochastic model is used for deception attacks, where the system states are corrupted by attackers. Under this framework, the system to be investigated is modeled as a new switched system. By using the constructed Lyapunov function, sufficient criteria are derived to guarantee the exponential mean-square stability and L ∞ performance. Subsequently, the corresponding controller is designed. Finally, the effectiveness of the dynamic ETS is illustrated by using an unmanned aerial vehicle system.
