该文研究输出反馈情形下线性定常连续及离散系统区域极点配置的统一代数刻划问题，即利用完全参数化方法，设计输出反馈控制器，使闭环极点配置于指定圆形区域内。文中导出了期望输出反馈控制器存在的充要条件，并进一步给出了这类控制器的全部参数化刻划。最后，得到了若干有益的推论，包括线性离散及连续系统稳定化控制器的统一代数表示等。
In this paper, we study the uniform algebraic scoring problem of the pole assignment of linear stationary continuous and discrete systems under the output feedback condition. That is, the output feedback controller is designed by the fully parametric method so that the closed-loop poles are located in the specified circular region. In this paper, the necessary and sufficient conditions for the existence of a desired output feedback controller are derived, and all parameterized scoring of such controllers is given. Finally, a number of useful inferences were obtained, including a unified algebraic representation of linear discrete and continuous system stabilization controllers.
