Abstract

The main goal of this project is to investigate the controllability of singular systems on time scales. More precisely, we will study the system on time scales given by\begin{equation}\left\{\begin{array}{lll}M x^{\Delta} (t) = Ax(t) + Bu(t), \vspace{2mm}\\y(t) = C x(t),\end{array}\right.\end{equation}where $x(t) \in \mathbb R^n$, $u(t) \in \mathbb R^m$, $y(t) \in \mathbb R^r$, $M, A \in \mathbb R^{n \times n}$, $B \in \mathbb R^{n \times m}$ and $C \in \mathbb R^{r \times n}$ are constant matrices and $M$ is a singular matrix. Also, we will investigate the existence of solutions for homogeneous and nonhomogeneous singular systems on time scales. We apply the variation of constants formula to characterize the controllability of singular control systems on time scales in terms of its parameters. (AU)
