建筑结构地震响应的MR阻尼器PID半主动控制

根据建筑结构的特点进行了结构上的简化计算,并采用了磁流变（MR）阻尼器的Bingham模型及PID半主动控制算法对建筑结构地震响应进行了半主动控制分析研究,并且与结构被动控制的效果进行了对比,数值结果表明：在EI-centro地震激励作用下,被动控制和半主动控制对结构地震响应的水平位移与速度取得了不同的控制效果;对结构的位移及速度的控制效果,MR半主动控制均明显的优于被动控制。

Magneto-Rheological dampers semi-active control of earthquake response for building structure with PID algorithm

According to characteristics of buildings structure, the simplified model was represented, in which the modified Bingham model of Magneto-Rheological（MR） dampers and the PID algorithm were used to study earthquake response of building structure with MR dampers semi-active control, and compared results of serni-active control with those of passive control. The results demonstrated that, under the semi-active control or passive control, there are some different controlling effects in horizontal displacement and velocity of structure subjected to EI- centro earthquake. The effect of semi-active control is better than that of passive control in controlling horizontal displacement and velocity.
