Design method study of hybrid control of semi-active tuned mass damper in combination with viscoelastic damper based on model of recurrent neural network with bias unit

基于神经-模糊控制理论和减震结构混合控制理论及相关的最新研究成果,提出了SATMD与基于RNNWBU模型的粘弹性阻尼器相结合混合控制体系的二阶段循环设计方法及其相应的设计步骤与设计过程流程图,并利用MATLAB语言编制了一套能对该混合控制体系进行弹塑性时程分析的计算机程序,使用该程序对结构进行弹塑性时程分析,并与试验结果相对比,分析表明二者吻合较好,从而实现了SATMD与基于RNNWBU模型的粘弹性阻尼器相结合混合控制体系的二阶段循环设计方法.本文设计方法是对抗震结构混合控制减震设计方法的进一步发展,对推动结构控制理论的发展具有理论意义和实用价值,因而具有广阔的发展前景.

Based on the neural-fuzzy control theory and the hybrid control theory of seismic reduction structure and studying results up to date, two phases circle design method and its designing step and flow chart of design are put forward for the hybrid control of semi-active tuned mass damper （SATMD） in combination with viscoelastic damper based on model of recurrent neural network with bias unit（RNNWBU）. A MATLAB program is developed to conduct elastoplastic time history analysis of the semi-active tuned mass damper （SATMD） in combination with viscoelastic damper based on the model of recurrent neural network with bias unit. It is inducted that the analysis result fits very well with the test result. And therefore two-phase circle design method has come true of the hybrid control of semi-active tuned mass damper （SATMD） in combination with viscoelastic damper based on model of recurrent neural network with bias unit. The method of this paper has made further development on the seismic reduction design method of hybrid control of aseismatic structure. The present work is of both theoretical and practical values in promoting the development of structural control theory, and therefore having a widely developing prospect.
