基于Benchmark模型的柔性大浮空结构模态参数辨识及振动主动控制方法

Identification of Modal Parameters and Active Vibration Control Method of Flexible Structures of Big Aerostat Based on Benchmark Model

为形成统一、标准、实用的柔性大浮空结构振动控制评价体系,本文提出了一种基于Benchmark模型的振控效果评价准则,并依此作为对整个研究进程进行指导和后续研究结果进行评价的标准。在此基础上论述了以基于模态参数辨识的振动主动控制为目标的试验与仿真横向并行的研究方法,该方法贯穿于浮空结构振动主动控制的整个纵向研究流程。

For establishing uniform, standard and practical vibration control and estimation system of flexible struc- tures of big aerostat, this paper proposed an evaluation criteria of vibration control effects based on Benchmark mod- el, which is used as the standard for guiding the whole research process and evaluating later research results. Then the paper discussed a horizontal research method of experiments and simulation for the purpose of active vibration control based on identification of modal parameters. And the method runs through the whole vertical research process of active vibration control of aerostat structures.
