Abstract: This paper generalizes the concept of disturbance-resistibility of systems from capability of a system to obviate external disturbance. Strict definition of disturbance-resistibility of systems is given. Necessary and sufficient conditions are shown for systems to be disturbance-resistible and for systems to achieve output regulation. A concrete algorithm is given which can bi used to test the disturbance-resistibility condition. Finally, this paper discusses the disturbance-resistibility of polynomial matrix systems and the structural property of compencators which can make the system a disturbance-resistible system.
