摘要： 在模态可控度及最小费用函数的基础上,针对目前因使用组合优化来布置作动器所带来的困难,采用遗传算法来确定振动主动控制中作动器的最优配置.为适于框架结构的具体计算,对常规遗传算法约束条件的引入进行了改进,最后给出了计算实例.算例表明这一方法是有效的.

Abstract: This paper is based on the modal degree of controllability and the least cost function with a view to overcoming the difficulties faced arising out of the application of combined optimization to disposition actuators. In the paper, the genetic algorithm is used to solve the optimal disposition in active vibration control. The introduction of constraint condition in to conventional genetic algorithm is improved to fit into the solution of frame structures. Finally, a numerical example is presented to show the effectiveness of the method.

Key words: frame, genetic algorithm, active control, optimal disposition
