摘要： 为减少框架结构振动主动控制所需控制能量,把结构设计与控制器设计相结合进行综合考虑,在保证框架结构基本性能和控制效果的前提下重新修改原结构以达到降低控制能量的目的.并把系统的稳定性、可控性等方面的因素作为约束条件,随机选择一组结构尺寸和材料常数通过系统降阶、控制率设计进而求得系统的控制能量,借助于改进的遗传算法进行随机寻优达到降低控制能量的目的.最后给出计算实例来表明此方法的有效性.

关键词: 框架结构, 控制能量, 可控性, 遗传算法

Abstract: In order to reduce control energy needed for active vibration control of frame structures, a mixed design which combines structural design with controller design is considered. The original structures are redesigned to diminish control energy without affecting the basic performance and control effect of frame structures. Using systemic stability, controllability and other factors as restrictive conditions, a random structural dimension and material constant are chosen to acquire control energy through system reduction and controller design. And an improved genetic algorithm is used to search for optimal control energy. Finally, a numerical example is provided to show the effectiveness of the method.

Key words: control energy, genetic algorithm, frame structures, controllability
