Abstract: The control problem for a class of nonlinear generalized delay Markov jump systems with generally uncertain transition rate is studied. First, a hybrid controller composed of a linear controller and an adaptive controller is designed for the unknown nonlinear parameters in the system, and a Lyapunov functional is constructed to make the trajectory of the system approach to the state space surface and the closed-loop system is admissible, satisfying Hcriteria γ. Furthermore, considering the characteristics of the generally uncertain transition rates matrices, a strict linear matrix inequality is constructed to make the conclusion more general. Finally, the effectiveness and feasibility of this control method are verified by numerical examples and image simulation.
