基于遗传算法的结构主动控制作动器优化布置
The Optimal Placement about Actuators of Active Structural Control Based on Genetic Algorithm
摘要
Abstract
The optimization of actuators of an active control structure under seismic excitation is studied. The random excitation is generated by equivalent excitation method, and the state space control algorithm is employed to calculate the dynamic responses. An optimized procedure based on genetic algorithm is proposed, in which a 0 -1 chromosome coding is used to resemble the spatial arrangement of actuators. Several typical cases are analyzed, in which the fitness objectives are composed of maximum acceleration response and maximum inter-story angle, while the structure is controlled by certain actuators. The results demonstrate that the proposed method is suitable and effective.关键词
