Abstract :
This paper mainly designs H∞ filters for switched discrete-time systems with uncertainties and time-delays under arbitrary switching sequences. According to Lyapunov theory, a sufficient condition guaranteeing the error systems of the filters to be asymptotically stable is developed without uncertainties. Then, by utilizing a lemma and the Schur complement formula, an existing condition of the robust H∞ filters for the switched systems is given. Finally, simulation results illustrate the feasibility and advantage of the robust H∞ filters.
