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. Switching impulse is considered in order to reduce the
error between theory and application, a sufficient condition for exponential stabilization of networked control systems under
a given switching rule is presented by multiple Lyapunov-like functions. These results are presented for both continuous-time
and discrete-time domains. Controllers are designed by means of linear matrix inequalities. Simulation results show the feasibility
and efficiency of the proposed method.
