Observer‐based hybrid‐triggered mechanism performance analysis of network control systems with two‐channel attacks

Abstract The main subject of this paper is to analyze the performance of observer‐based hybrid‐triggered mechanism network control systems that are affected by dual cyber attacks. Firstly, facing this problem of unobservable system state, an observer model is introduced, which also establishes a solid theoretical foundation for subsequent controller design. Secondly, during data transmission, the systems are vulnerable to dual cyber attacks: The controller may face the threat of false data injection when it receives information from the observer, while the controller faces the threat of denial‐of‐service attacks when sending commands to the actuator. Thirdly, Lyapunov functions and linear matrix inequalities are employed to ensure that the resulting closed‐loop system is asymptotically mean‐square stabilized under the prescribed performance. Finally, a simulation example is given to demonstrate the effectiveness of the method in this paper.
