Abstract
En 中文
This paper focuses on the dynamic event-triggered mechanism (DETM) of the Cyber-Physical-Systems (CPSs) under multi-channel hybrid cyber-attacks based on the observer. The hybrid cyber-attack in this article contains Denial of Service (DoS) attacks, deception attacks, and replay attacks, which do not affect each other and attack the network channel. By constructing DETM, Lyapunov equation and linear matrix inequality (LMI), the system maintains the 𝐻∞ H∞$$ {H}_{\infty } $$ performance of suppressing external disturbances and the 𝐻2 H2$$ {H}_2 $$ performance of constraining output energy. In the case where the system status is difficult to observe directly, an observer is introduced to estimate the system status. Finally, the effectiveness of the above method is verified by a simulation example.
