Digital libraries of video are rapidly growing in size and availability through digital networks of computers . The explosion of digital unstructure information , such as video , traveling through the network raises the need for tools that allow video information structuring and ‘‘intelligent’’ access to sequences . In this paper we present a novel video(More)
In this paper, the theories and methods of modeling of dynamic regions soft partitioning for complex process systems was researched. Every dynamic sub-region is one aggregation which including continuous variables and discrete events, and their mutual actions. At the same time, every dynamic sub-region is one unit, which has its dynamic characters and(More)
This paper investigates the problem of state feedback H<sub>&#x221E;</sub> control for singular systems through delta operator approach. Firstly, a bounded real lemma corresponding to a singular continuous system under the framework of the delta operator model is obtained. Then, the existence condition and explicit expression of a desirable(More)
This paper has studied the problem of the exponential stability for uncertain systems with time-varying delay. According to Wirtinger's inequality method a new criteria is derived based on a linear matrix inequality and convex combination approach to dispose the time-delay in the derivative of Lyapunov-Krasovskii's function. Finally, this paper has used(More)
This paper investigates the problem of state feedback H∞ control for singular systems through delta operator approach. Firstly, a bounded real lemma corresponding to a singular continuous system under the framework of the delta operator model is obtained. Then, the existence condition and explicit expression of a desirable H∞ controller for the singular(More)
This paper studies the problem of designing an observer-based admissible controller for singular delta operator systems. Sufficient conditions are provided for the existence of an asymptotical and physically realizable observer. Then an observer-based admissible controller is obtained in terms of strict linear matrix inequalities. The corresponding gain(More)
