This paper deals with a new disturbance-observer-based event-triggered control strategy for semi-Markovian jump systems(S-MJS), which with nonlinearity and multiple disturbances. The designed observer is firstly performed to review the disturbance caused by an exogenous dynamic system. Meantime, by combining the output of the disturbance observer with state feedback control law, the control strategy is implemented such that the considered closed-loop system is stochastically stable. Combined with the stochastic analysis techniques and linear matrix inequalities (LMIs), some adequate terms for the solvability of the proposed problem are derived. Lastly, the feasibility of this strategy is verified by the simulation.
