Simultaneous Stabilization And Control For Inter-connected Large-scale System With Time-delay

In the natural sciences and engineering systems, the uncertainty is always inveitable. The uncertainty can reflect the substantial control process, accurately, and manifest the external disturbance and the parameter variation of the system.With the development and progress of the society, appearing complicated structure, large and strong correlation system-large scale system.For these large systems, considering uncertainty and the time-delay not only increse the diffculty in the analysis and the practice application, therefore, there are important theoetic and practical significance in the robust stability and control of the uncertain large-scale system with time-delay. This paper studies the interconnected large-scale systems with time delay stabilization and control. The primary tasks are as follows:Firstly, A class of uncertain time-delay systems is studied simultaneous Stabilization problem, based on the functional of Lyapunov-Krassorvskii and linear matrix inequality approach. The uncertain time-delay and sufficient conditions for the simultaneous Stabilization of closed-loop system.Secondly, in view of the uncertain time-delay systems, Robust control problem is studied,using the linear matrix inequality method,the system is given a sufficient condition for the existence of the robust control law design and also given an method of state FeedbackThirdly, simultaneous stabilization of a class of large scale Interconnected systems is studied, similar to the interconnected large-scale system fault tolerant control research methods, through constructing Lyapunov-Krassorvskii functional and linear matrix Inequality methodsFinally, the output feedback control for a class of time-delay systems.
