<p>This paper presents a dynamic event-triggered sliding mode control strategy to resist dual-channel hybrid cyber-attacks and reduce network communication load. Firstly, a improved dynamic event-triggered mechanism is introduced to regulate network communication by considering the presence of denial-of-service and deception attacks in both the forward and feedback channels. The nonlinear closed-loop system considering external disturbances, network delay, and dual-channel hybrid cyber-attacks is described by the Takagi-Sugeno fuzzy model. Then, a stability criterion is derived using the Lyapunov–Krasovskii method, and a co-design method for the dynamic event trigger and controller in the form of linear matrix inequalities is given. Further, the reachability of the designed integral sliding mode control law is demonstrated. Finally, the simulation results show that the proposed method can resist external disturbances and hybrid cyber-attacks, reducing communication requirements while guaranteeing control performance.</p>
