摘要: 本文把系统排除"外部干扰"的能力概括为系统的"能抗干性",给出了"能抗干性"的严格 定义,证明了系统为"能抗干"的充分必要条件及系统达到"输出调节"的充分必要条件,提出了 检验"能抗干性"的具体算法.最后,讨论了多项式阵系统的"能抗干性"条件及实现"能抗干性" 的补偿器结构.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.
