Hybrid-Triggered H_∞ Control for Networked Control Systems With Deception Attacks

For discrete networked control systems with deception attacks, the problem of ${\mathcal {H}}_ {\infty } $ output feedback control based on hybrid event triggered is studied. Firstly, we propose a novel hybrid-triggered mechanism to save effect of network bandwith. Secondly, considering the impact of deception attacks, a cooperative control method with hybrid event triggered and observer-based output feedback is obtained. We derive some new sufficient conditions for the stability and ${\mathcal {H}}_ {\infty } $ performance of the networked control systems by constructing a new type of Lyapunov function and using linear matrix inequality, etc. At the same time, we obtain observer and control gain matrix. Finally, we give the simulation example to prove feasibility and rationality of the control strategy.
