This paper is devoted to analysis of relative controllability of semilinear delay differential
systems with linear parts defined by permutable matrices. By introducing a notion of delay …

This paper investigates the relative controllability of delay differential systems with linear
impulses and linear parts defined by permutable matrices. We use the impulsive delay …

In this paper, we mainly study a class of conformable impulsive delay differential equations
(CIDDEs). We first define a conformable impulsive delayed matrix function, and construct an …

In this paper, we study a class of neutral time-delay control systems. The relative
controllability of the linear system is given by constructing the corresponding neutral delay …

In this paper, we study the controllability of a system governed by second order delay
differential equations. We introduce a delay Gramian matrix involving the delayed matrix …

This study uses a delayed matrix exponential to illustrate the solution of both linear and
nonlinear delay problems using permutable matrices. We outline several prerequisites that …

This paper investigates relative controllability of impulsive linear discrete delay systems with
constant coefficients and a pure delay. Grammian and rank criteria for relative controllability …

In this paper, relative controllability of impulsive multi-delay differential systems in finite
dimensional space are studied. By introducing the impulsive multi-delay Gramian matrix, a …

In this work, with the aid of the representation of the solution, the relative controllability for
delaying linear discrete systems with a second-order difference is principally investigated …
