Abstract

In this paper we discuss the robustness of a general system with additive perturbation which includes parameter perturbation and perturbed control action.The gain margin for robust stability will be given.We show that thegain margin,defined as robustness degree,is a sufficient condition for the robust stability of a system with certain perturbations.
