文章针对地震作用下高层建筑结构半主动控制问题,引入分散控制的策略,将模糊逻辑理论与遗传算法原理相结合,应用遗传算法优化子系统模糊规则库,提出分散遗传-模糊控制(decentralized genetic-fuzzycontrol,简称DGFC)算法,并应用于高层结构振动控制中,通过MR阻尼器实现结构地震反应控制;对某20层钢结构Benchmark结构模型进行数值计算与分析,结果表明,DGFC算法可以有效地抑制结构地震反应,且保证了系统鲁棒性和可靠性。
In this paper, aiming at the semi-active control of high-rise buildings under earthquake, the strategy of decentralized control is introduced. Combining the theory of fuzzy logic and the principle of genetic algorithm, the genetic algorithm is used to optimize the fuzzy rule base of sub-system and decentralized genetic- Fuzzycontrol, referred to as DGFC) algorithm, and applied to the vibration control of high-rise structures, the seismic response control of the structure was realized by MR dampers. The numerical simulation and analysis of the Benchmark structure model of a 20-story steel structure showed that the DGFC algorithm can effectively suppress Structural seismic response, and ensure system robustness and reliability.
