Stability analysis of time–varying perturbed descriptor systems

The manuscript deals with the analytical study of the "practical" stability of linear time dependent descriptor perturbed systems. The paper works out and proves the sufficient conditions (posed as LMIs) for practical stability of perturbed singular systems. The Gamidov's type integral inequality is used as a tool in the proof of the sufficient conditions of practical stability for perturbed singular systems. Finally, numerical examples are given to illustrate the effectiveness of the proposed approach.
