Robust stabilization for a class of nonlinear networked control systems

The problem of robust stabilization for a class of uncertain networked control systems (NCSs) with non-linearities satisfying a given sector condition is investigated in this paper. By introducing a new model of NCSs with parameter uncertainty,network-induced delay,nonlinearity and data packet dropout in the transmission,a strict linear ma-trix inequality (LMI) criterion is proposed for robust stabilization of the uncertain nonlinear NCSs based on the Lyapunov stability theory. The maximum allowable transfer interval (MATI) can be derived by solving the feasibility problem of the corresponding LMI. Some numerical examples are provided to demonstrate the applicability of the proposed algorithm.
