Stability of Positive Differential Systems With Delay

IEEE Transactions on Automatic Control, 2013
We first prove an explicit criterion for positive linear time-varying differential systems with distributed delay. Then some simple criteria for exponential stability of positive linear time-invariant differential systems with delay are presented.

Minimal Differential Difference Realizations of Delay Differential, Differential Difference, and Neutral Delay Systems

IEEE Control Systems Letters, 2021
Delay-Differential Equations (DDEs) are often used to represent control of and over large networks. However, the presence of delay makes the problems of analysis and control of such networks challenging. Recently, Differential Difference Equations (DDFs) have been proposed as a modelling framework which allows us to more efficiently represent the low ...

Stability and stabilization of delay differential systems

Automatica, 1996
This paper considers the stability and stabilization of the following linear systems with delay \[ \dot y(t)= A_0y(t) +\sum^p_{i=1} A_iy (t-\tau_i) +EW(t), \quad t\geq t_0, \] under bounded additive disturbance. Conditions for respecting linear constraints and for asymptotic stability are obtained from a characterization of positive invariance ...

A Ring of Delay Operators with Applications to Delay-Differential Systems

SIAM Journal on Control and Optimization, 1977
A ring of delay operators is used to obtain a representation of the solution of systems of linear delay-differential equations. With the aid of this representation an algebraic rank-test is obtained for the $R^n $-controllability of the systems.

Decoupled delay estimation in the identification of differential delay systems

Automatica, 1984
Using a variable projection functional in nonlinear least-squares theory, the authors show ''how the least-squares estimation of pure time delay can be decoupled from the estimation of the remaining system parameters for a class of differential delay models''. Some advantages of this approach are discussed and several simulation results are presented.
