【Abstract】 For a class of networked control systems with random delay and nonlinear perturbation,by applying variableperiod sampling method,the discretization of networked control systems is modeled as a nonlinear Markovian jump systems with partly unknown transition probabilities.By means of the stochastic Lyapunov method,a sufficient condition is presented,which guarantees the stochastical stability of the closed-loop system and at the same time maximizes the bound on the nonlinearity.A simulation example is presented to illustrate the effectiveness of the proposed method.更多还原
