Distributed Delays (distributed + delay)
Selected AbstractsRobust H, Non-Fragile Controller Design for Uncertain Descriptor Systems with Time-Varying Discrete and Distributed DelaysASIA-PACIFIC JOURNAL OF CHEMICAL ENGINEERING, Issue 3-4 2005Dong Yue This paper is concerned with the design problem of non-fragile H, controller for uncertain descriptor systems with time-varying discrete and distributed delays and controller gain variations. The designed controller is shown to be robust not only to parameter uncertainties, but also to errors in the controller coefficients. The obtained criterion to derive an efficient non-fragile H, control design is expressed as a set of nonconvex matrix inequalities, which can be solved by combining both linear matrix inequalities technique and come complementarity method. A numerical example is given to demonstrate effectiveness of the proposed methods. [source] Distributed delay constrained multicast routing algorithm with efficient fault recoveryNETWORKS: AN INTERNATIONAL JOURNAL, Issue 1 2006Hasan Ural Abstract Existing distributed delay constrained multicast routing algorithms construct a multicast tree in a sequential fashion and need to be restarted when failures occur during the multicast tree construction phase or during an on-going multicast session. This article proposes an efficient distributed delay constrained multicast routing algorithm that constructs a multicast tree in a concurrent fashion by taking advantage of the concurrency in the underlying distributed computation. The proposed algorithm has a message complexity of O(mn) and time complexity of O(n) in the worst case, where m is the number of destinations and n is the number of nodes in the network. It constructs multicast trees with the same tree costs as the ones constructed by well-known algorithms such as DKPP and DSHP while utilizing 409 to 1734 times fewer messages and 56 to 364 times less time than these algorithms under comparable success rate ratios. The proposed algorithm has been augmented with a fault recovery mechanism that efficiently constructs a multicast tree when failures occur during the tree construction phase and recovers from any failure in the multicast tree during an on-going multicast session without interrupting the running traffic on the unaffected portion of the tree. © 2005 Wiley Periodicals, Inc.

GoodallArticle first published online: 28 DEC 200 Abstract A feedback stabilization problem is investigated for a class of imperfectly known implicit systems with discrete and distributed delays. The imperfections acting on the systems, which may be time-, state-, delayed state-, and/or input-dependent, are modelled as additive nonlinear perturbations influencing a known set of nonlinear functional differential equations of the neutral type. Sufficient conditions, which include a delay-dependent matrix inequality and a delay-dependent stability criterion involving some bounding parameters for the uncertainty in the system, are presented and a class of robust feedback stabilizers, including both memoryless and those with memory, are designed to guarantee a prescribed stability property for the class of implicit systems.

[source] Design of robust non-fragile H, filters for uncertain neutral stochastic systems with distributed delays,ASIAN JOURNAL OF CONTROL, Issue 1 2010Bo Song Abstract This paper deals with the problem of robust non-fragile H, filtering for neutral stochastic systems with distributed delays and norm-bounded parameter uncertainties. Attention is focused on the design of a filter which is subject to gain variations, such that the filtering error system is robustly stochastically stable with a prescribed H, performance level for all admissible uncertainties. A delay-dependent sufficient condition for the solvability of this problem is obtained in terms of a linear matrix inequality.

The purpose is to design a memory controller, which guarantees that the resulting closed-loop system is mean-square asymptotically stable. In terms of a set of linear matrix inequalities, a delay-dependent condition is proposed and a robust memory controller is designed. Two numerical examples are provided to illustrate the effectiveness of the proposed method.
