摘　　要：本文在简单介绍H~∞最优敏感性设计理论的基础上,研究了广义系统的一些频域特性;提出了一种用H~∞方法设计反馈控制器以消除广义系统的脉冲模,并使系统稳定且敏感性最小的频域设计方法;同时给出了设计步骤,并用算例说明了设计过程。In this paper, some frequency characteristics of SISO descriptor systems are first investigated after a brief introduction of the H~∞-optimal sensitivity theory. Then, a new frequency domain theory for designing the feedback controllers of SISO descriptor systems is proposed, which can eliminate the impulsive modes, stabilize the systems and obtain the minimal sensitivity. Furthermore, a practical sub-optimal design method is presented. At last, an example is given to demonstrate the designing procedure.
