| Abstract: | The hyperstability property of switched systems was investigated.The imported energy of each subsystem is from the input of the switched system or from the other subsystems.The whole imported energy of each subsystem was restricted by the Popov inequality with modified integral interval.Under the conditions that all the subsystems have finite imported energy,the hyperstability and asymptotical hyperstability of switched systems were studied on the basis of the dissipative theory of switched systems.According to the positive real lemma and Kalman-Yakubovich-Popov lemma,sufficient conditions were given which made the switched system have hyperstability and asymptotical hyperstability when switching signals were slow.Simulation results verified the conclusion. |
