Stability and assignment of spectrum in systems with discrete time lags
De la Sen Parte, Manuel 
(Hindawi Publishing Corporation, 2006)
(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
De la Sen Parte, Manuel ; Bilbao Guillerna, A. (Hindawi Publishing Corporation, 2005)
; Bilbao Guillerna, A. (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 ...
Robustly stable multiestimation scheme for adaptive control and identification with model reduction issues
Bilbao Guillerna, A.; De la Sen Parte, Manuel ; Ibeas Hernández, Asier ; (Hindawi Publishing Corporation, 2005)
; Ibeas Hernández, Asier ; (Hindawi Publishing Corporation, 2005)
A discrete pole-placement-based and multiestimation-based adaptive control scheme involving a relative adaptation dead zone is presented for a plant with known poles and unknown zeros., The basic usefulness of the proposed ...
Adaptive control of time-invariant systems with discrete delays subject to multiestimation
De la Sen Parte, Manuel ; (Hindawi Publishing Corporation, 2006)
; (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
De la Sen Parte, Manuel (Hindawi Publishing Corporation, 2006)
(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 ...
Model-matching-based control of the Beverton-Holt equation in Ecology
De la Sen Parte, Manuel ; (Hindawi Publishing Corporation, 2008)
; (Hindawi Publishing Corporation, 2008)
Beverton-Holt equation of Ecology has a prescribed solution. The way used to achieve the tracking objective is the design of a carrying capacity through a feedback law so that the prescribed reference sequence, which defines ...
Adaptive control of single-input single-output hybrid systems possessing interacting discrete- and continuous-time dynamics
De la Sen Parte, Manuel (Hindawi Publishing Corporation, 2005)
(Hindawi Publishing Corporation, 2005)
This paper deals with the problem of synthesizing a robust adaptive controller for a specific class of single-input single-output (SISO) time-invariant hybrid controlled object (plant) which can operate under bounded ...
On the Global Asymptotic Stability of Switched Linear Time-Varying Systems with Constant Point Delays
De la Sen Parte, Manuel ; Ibeas Hernández, Asier (Hindawi Publishing Corporation, 2008)
; Ibeas Hernández, Asier (Hindawi Publishing Corporation, 2008)
This paper investigates the asymptotic stability of switched linear time-varying systems with constant point delays under not very stringent conditions on the matrix functions of parameters. Such conditions are their ...
Stability Results of a Class of Hybrid Systems under Switched Continuous-Time and Discrete-Time Control
De la Sen Parte, Manuel ; Ibeas Hernández, Asier (Hindawi Publishing Corporation, 2009)
; Ibeas Hernández, Asier (Hindawi Publishing Corporation, 2009)
This paper investigates the stability properties of a class of switched systems possessing several linear time-invariant parameterizations (or configurations) which are governed by a switching law. It is assumed that the ...
On the properties of reachability, observability, controllability, and constructibility of discrete-time positive time-invariant linear systems with aperiodic choice of the sampling instants
De la Sen Parte, Manuel (Hindawi Publishing Corporation, 2007)
(Hindawi Publishing Corporation, 2007)
This paper investigates the properties of reachability, observability, controllability, and constructibility of positive discrete-time linear time-invariant dynamic systems when the sampling instants are chosen aperiodically. ...
