一类用于结构振动控制的输出反馈控制器的设计

Design of a Kind of Output Feedback Controllers for Structural Vibration Control

本文探讨一类设计简捷的直接输出反馈控制器应用于结构振动控制的设计问题，在导得的计及作动机构动特性的结构振动控制特性的基础上，提出了两种设计准则及其设计方法以及必须解决的设计前提。文末以两算例（提高结构模态阻尼与稳定性控制）说明本设计准则与方法的应用，以及其控制效果。

The design problem of a kind of direct output feedback controllers for structural vibration control isstudied in the paper. Two kinds of design criteria and methods are presented based on the deduced characteristics of the structural vibration control concerned with the characteristic of the actuators. Some designprerequisites are emphasized. At the end of the paper two calculation examples (structural modal dampingenhancement and stability control) are given to demonstrate the applications of the design criteria andmethods the effectiveness of the control.
