In this paper, we analyze the concept of observability in the case of conformable time-invariant linear control systems. Also, we study the Gramian observability matrix of the conformable linear system, its rank criteria, null space, and some other conditions. We also discuss some properties of conformable Laplace transform.

Keywords: Conformable operator, time-invariant linear control systems, Gramian observability matrix, conformable Laplace transform.
