Pairs of k-step reachability and m-step observability matrices
Special Matrices, 2013 Let $V$ and $W$ be matrices of size $ n \times pk$ and $q m \times n $, respectively. A necessary and sufficient condition is given for the existence of a triple $(A,B,C)$ such that $V$ a $k$-step reachability matrix of $(A,B)$ and $W$ an $m$-step ...

An analysis on approximate controllability of semilinear control systems with impulsive effects
Alexandria Engineering Journal, 2022 The article uses semigroup theory and Gronwall’s inequality to investigate the approximate controllability of impulsive semilinear control systems. A weaker Lipschitz condition on nonlinearity is enforced to reach the main conclusions.

Yellow virus epidemiological analysis in red chili plants using Mittag-Leffler kernel
Alexandria Engineering Journal, 2023 This scientific study investigates to check the dynamical behavior of yellow virus in red chilli with fractional order techniques. While attempts are being made to stop the yellow virus pandemic, a more infectious yellow virus found in red chilli is ...

Numerical approach to the controllability of fractional order impulsive differential equations
Demonstratio Mathematica, 2020 In this manuscript, a numerical approach for the stronger concept of exact controllability (total controllability) is provided. The proposed control problem is a nonlinear fractional differential equation of order α∈(1,2]\alpha \in (1,2] with non ...

Theoretical observers for infinite dimensional skew-symmetric systems
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020 The observer construction has a main importance in the control theory and its applications for the systems of infinite dimension. Even if the system’ state has an infinite dimension, its estimation is given using some physical measures of finite ...
