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.
