Abstract: This paper discusses the problem of robust input-output stability of Lur'e systems. The system's perturbation margins, which will enable the system to maintain input-output stability in the presence of both linear element and nonlinear element perturbations, are given. In addition, two examples are given to illustrate the effectiveness of the perturbation margins.-
