Stability Analysis of a Class of Nonlinear MIMO Networked Control Systems

The issue of stability analysis for nonlinear MIMO networked control systems (NCSs) is researched, where its network transmission is connected with network-induced delay and packet dropout. The effect of network-induced delay to the stability of nonlinear networked control system s is considered. Asymptotical stability under a multiple-packet transmission policy is analyzed and the maximum allowable delay conditions for systems are derived by using time-delay system theory and the 2nd Lyapunov method. Then based on the research of Lyapunov-Krasovskii theory, the LMI´s conditions for asymptotic stability are derived. The efficacy and feasibility of the proposed methods is shown by presenting simulation results from nonlinear networked control example.
