The devlopment of switched systems, especialy of rank one difference systems, in recent years are reviewed in this paper.Widely engaged with engeering applications, these systems are of great importance. The stability of a class of rank one difference time-discreted switched system is studied in this paper, and the necessary and sufficient con-dition for the asymptotic stablity of the system is obtained by combining the techniques Metzler and the Hurwitz matrix. |
