Common Fixed Points of Generalized Rational Type Cocyclic Mappings in Multiplicative Metric Spaces
(Hindawi Publishing Corporation, 2015)
The aim of this paper is to present fixed point result of mappings satisfying a generalized rational contractive condition in the setup of multiplicative metric spaces. As an application, we obtain a common fixed point of ...
Adaptive control of time-invariant systems with discrete delays subject to multiestimation
(Hindawi Publishing Corporation, 2006)
This paper deals with a robustly stable adaptive pole-placement-based controller for time-delay linear systems with unknown point delays within known intervals of sufficiently small lengths under unmodeled dynamics and ...
Stabilization criteria for continuous linear time-invariant systems with constant lags
(Hindawi Publishing Corporation, 2006)
Some criteria for asymptotic stability of linear and time-invariant systems with constant point delays are derived. Such criteria are concerned with the properties of robust stability related to two relevant auxiliary ...
Stability and assignment of spectrum in systems with discrete time lags
(Hindawi Publishing Corporation, 2006)
The asymptotic stability with a prescribed degree of time delayed systems subject to multiple bounded discrete delays has received important attention in the last years. It is basically proved that the alpha-stability ...
Fractional hold circuits versus positive realness of discrete transfer functions
(Hindawi Publishing Corporation, 2005)
The appropriate use of fractional-order holds(beta-FROH) of correcting gains beta is an element of[- 1,1] as an alternative to the classical zero- and first-order holds(ZOHs, FOHs) is discussed related to the positive ...
About the stability and positivity of a class of discrete nonlinear systems of difference equations
(Hindawi Publishing Corporation, 2008)
This paper investigates stability conditions and positivity of the solutions of a coupled set of nonlinear difference equations under very generic conditions of the nonlinear real functions which are assumed to be bounded ...
On Chebyshev's Systems and Non-Uniform Sampling Related to Caputo Fractional Dynamic Time-Invariant Systems
(Hindawi Publishing Corporation, 2010)
This paper is concerned with the investigation of the controllability and observability of Caputo fractional differential linear systems of any real order α. Expressions for the expansions of the evolution operators in ...
Robust Adaptive Stabilization of Linear Time-Invariant Dynamic Systems by Using Fractional-Order Holds and Multirate Sampling Controls
(Hindawi Publishing Corporation, 2010-02)
This paper presents a strategy for designing a robust discrete-time adaptive controller for stabilizing linear time-invariant (LTI) continuous-time dynamic systems. Such systems may be unstable and noninversely stable in ...
Observer-Based Vaccination Strategy for a True Mass Action SEIR Epidemic Model with Potential Estimation of All the Populations
(Hindawi Publishing Corporation, 2011)
This paper presents a simple continuous-time linear vaccination-based control strategy for a SEIR (susceptible plus infected plus infectious plus removed populations) propagation disease model. The model takes into account ...
On the Extensions of Krasnoselskii-Type Theorems to p-Cyclic Self-Mappings in Banach Spaces
(Hindawi Publishing Corporation, 2011)
A set of np(>= 2)-cyclic and either continuous or contractive self-mappings, with at least one of them being contractive, which are defined on a set of subsets of a Banach space, are considered to build a composed self-mapping ...
