基于二进制型粒子群算法的相邻两结构主动控制系统安装位置优化

OPTIMAL PLACEMENT OF ACTIVE CONTROL SYSTEMS IN ADJACENT BUILDINGS BASED ON THE BINARY PARTICLE SWARM OPTIMIZATION

用作动器将两相邻结构的一些楼层连接,以使两结构的动力响应都得到控制的方法具有较高的实用价值,而确定作动器沿楼层的合理安装位置是关键问题。将多亲杂交算子引入传统的粒子群优化算法,提出了一种二进制型粒子群优化算法来解决相邻两结构主动控制系统安装位置的优化问题。结果表明,综合考虑控制效果与控制力付出,将相邻两结构间的作动器布置在靠近结构顶部是有效的。

Connecting two adjacent buildings with actuators to reduce the dynamic responses of the two buildings is a valuable method,and the optimal placement of actuators along floors is an important issue.A binary particle swarm optimization(PSO) is proposed by incorporating multi-parent crossover operator into the traditional PSO to solve the optimal placement of actuators.The numerical example indicates that the placement of actuators near the top of buildings is efficient in view of the trade-off between control effects and control efforts.
