摘要

通过对多层结构在二维地震动作用下的控制算法和控制机构布置准则的分析,建立了控制机构的布置优化模型,利用改进的遗传算法中二进制单点交叉,避免了用惩罚函数。以一栋带有阻尼器控制的结构为例,进行了数值计算和分析,结果与穷举法比较表明,本文优化算法是快速而有效的。
Active control algorithm and actuator configuration criterion for multi-story structures subjected to multi-dimensional earthquake excitations are investigated. The mathematical model of optimal actuator configuration is established and an improved genetic algorithm is used in crossover operation to avoid constraint violations. The numerical calculation and analysis are carried out for a building structure controlled by several dampers. Simulation results indicate that the convergent speed of approach presented in the paper is faster as compared to exhaustive method.
