Abstract

This paper deals with the problem of switching between an open-loop estimator and a close-loop estimator for compensating transmission error and packet dropout of networked control systems. An average dwell time scheme and piecewise Lyapunov function method are used to analyze the exponential stability of such closed loop system. Given the maximal packet dropout rate, a sufficient condition for exponential stability under average dwell time is presented. An exponential decay degree and a lower bound of average dwell time are explicitly given. Switching controllers are designed by means of linear matrix inequalities
