摘要
对磁流变阻尼器的性能及恢复力模型进行了介绍 ,并对其参数进行了设计 ,提出了基于经典线性最优控制算法和瞬时最优控制算法的半主动控制律。通过对一装有七个MR阻尼器的七层框架结构的地震反应分析表明 ,基于这两种控制算法的半主动控制律是非常有效的 ,并且该半主动控制方法能够有效地减小结构的地震反应。
The performance and restoring model of a magnetro?rheological (MR)damper are introduced, and the determination of parameters of the damper is discussed. A semi?active control rule based on the classical optimal control algorithm and instantaneous optimal control algorithm is proposed in the paper. It is to be noted that to proof the feasibility of the proposed control rule. A test is made on the seismic responses of a seven?story frame structure with seven MR dampers. The results have shown that the control rule based on two kinds of control algorithms is very effective. It is obvious to show that the structural responses induced by earthquake are reduced.
