ABSTRACT This paper investigates the event‐triggered control problem for networked control systems (NCSs) subject to denial‐of‐service (DoS) attacks. To capture the impact of aperiodic attack patterns, a stochastic DoS attack model is developed based on the Bernoulli distribution. This model provides a more realistic characterization of the randomness of cyber‐attacks, overcoming the limitation of conventional periodic attack assumptions. To conserve communication resources under DoS attacks, a switching‐like dynamic event‐triggered mechanism (SDETM) is developed. The SDETM combines the advantages of mode switching and dynamic triggering, enabling autonomous selection of the triggering policy according to the network status and adaptive adjustment of the triggering threshold based on the system state. Furthermore, considering the potential for actuator faults in practice, an actuator fault model is incorporated into the NCS framework. An controller is then designed to ensure satisfactory stability and performance despite stochastic packet loss. By employing Lyapunov stability theory and linear matrix inequality (LMI) techniques, sufficient conditions for asymptotic stability are derived, meanwhile, a design method for the control gains is provided. Numerical simulations validate the effectiveness of the proposed control scheme.
