摘　　要：基于抗震结构混合控制理论和神经-P315模糊控制理论,建立了PTMD与基于RNNWBU模型的粘弹性阻尼器相结合混合控制体系的运动模糊微分方程并得到其解,提出了该混合控制体系的二阶段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基于模糊的弹塑性时程分析的计算机程序,使用该程序对受控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PTMD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设计方法,是对减震结构混合控制抗震设计方法的进一步发展.Based on the hybrid control theory of aseismatic structure and the neural-fuzzy control theory, fuzzy motion differential equations are established for hybrid control system of the passive tuned mass damper （PTMD） in combination with viscoelastic damper based on model of recurrent neural network with bias（RNNWBU）, and their solutions are acquired. Two phase design method and its designing step and flow chart of design are put forward for the hybrid control system. A MATLAB program is developed to conduct elastoplastic time history analysis of the hybrid control system. It is indicated that the analysis result fits very well with the test result. Therefore the two-phases design method has come true of the hybrid control system of the passive tuned mass damper in combination with viscoelastic damper based on model of recurrent neural network with bias. This paper has made further development on the aseismatic design method of hybrid control of seismic reduction structure and played an important role in promoting the development of the theory of structural control, and therefore has a widely developing prospect.
