Abstract :
This paper is concerned with robust stability of uncertain packet-based networked control systems (NCSs) with time-varying transmission delays and intervals based on input delay approach. The parameter uncertainty is assumed to be norm-bounded. An independent and nonidentically distributed process is proposed to model the real-time distribution of input delays. The NCSs are modeled as a hybrid system with multiple input-delay subsystems. With appropriate Lyapunov-Krasovskii functional and bounding techniques, delay-distribution-dependent sufficient conditions are established for the robust exponential stability of the overall system. Numerical example shows the effectiveness of our results.
