Abstract. In this paper, the stability robustness of particular class of linear systems in the time domain, is addressed using the Lyapunov approach. The bounds of unstructured perturbation vector function, that maintain the stability of the nominal system with attractivity property of subclass of solutions are obtained both for regular and irregular linear singular systems.
Key words. Generalized state-space systems, attraction property, Lyapunov stability, robustness.

LJAPUNOVSKA ROBUSTNOST STABILNOSTI LINEARNIH SINGULARNIH SISTEMA: NOVI REZULTATI
U ovom radu razmatrana je osobina privlačenja nultog ravnotežnog stanja linearnog singularnog sistema i pripadajuća osobina robusnosti u odnosu na linearne nestrukturne perturbacije. Izvedene i dokazane teoreme predstavljaju znatno proširenje rezultata do kojih su autori došli ranije, a istovremeno jasno ukazuju na široke mogućnosti primene postojećih rezultata na analizu robusnosti stabilnosti razmatrane klase sistema.
