Development of Hybrid Experimental Technique for Seismic Control of Civil Structures

为了实现一个实用的控制装置的主动质量驱动器（AMD）类型的高层建筑，我们开发了一种新的闭环开环最优控制算法，已通过最小化的总和的二次时变性能指标和地震能量输入到结构系统。这种新的控制律为AMD系统和地震激励结构的应用提供了易于实现的控制算法。由于控制力不依赖于结构系统的刚度，该优化算法简单可靠，可用于在线控制。研究了两个权矩阵和一个表示输入结构地震能量大小的参数对控制效果的影响。这种新的算法已被引入到一个模型的八层建筑，以证明减少由中等地震引起的振动。

To realize a practical control device of active mass driver (AMD) type for high-rise buildings we developed a new closed-open-loop optimal control algorithm that has been derived by minimizing the sum of the quadratic time-dependent performance index and the seismic energy input to the structural system. This new control law provides feasible control algorithms that can easily be implemented for AMD system and applications to seismic-excited structures. This optimal algorithm is simple and reliable for on-line control operations because control force does not depend on the rigidity of structural system. We investigate the effects of two weighting matrices and a parameter expressing amount of input seismic energy to structure on the control efficieny. This new algorithm has been introduced to a model eight-story building to demonstrate reduction of vibrations caused by medium earthquakes.
