This paper studies the observer-based exte-nded dissipative dynamic probabilistic event-triggered control problem for Markov jump systems subject to actuator failures and hybrid cyber-attacks. Both deception attacks and denial-of-service attacks are involved, with deception attacks occurring in the sensor-observer channel and denial-of-service attacks occurring in the observer-controller channel. Two independent dynamic probabilistic event-triggered mechanisms are established and applied to the sensor-observer channel and the observer-controller channel respectively to conserve network resources, upon which an observer-based event-triggered controller is designed. Considering the stochastic actuator failure, sufficient criteria ensuring stochastic stability and extended dissipativity for Markov jump systems are proposed through the Lyapunov theory and stochastic analysis. Then, a design algorithm for the observer gains, controller gains, and event-triggering weight matrices is presented based on the established conditions. Finally, for the sake of justifying the effectiveness of the proposed algorithm, an application-oriented example of the boost converter circuit system is provided.
