構造物のARXモデルとアクティブマスダンパの運動方程式に基づく振動制御

抄録

Structural control and system identification are integrated to directly utilize the results of system identification of an objective structure for its active control. After the structure is expressed as ARX models and an active mass damper (AMD) is expressed as the motion of equation, a state equation and an output equation for the AMD-structure system are introduced in the discrete-time space. By considering the zero-th terms for input signals in the ARX models, the formulation and the optimal regulator problem can be generally applied to building structures. As the measurements, the feedback control law requires the AMD's velocity and stroke and the structure's acceleration at least. Numerical examples indicate high applicability of the proposed control strategy to MDOF structures. The earthquake response analysis and the poles of the AMD-structure system confirm the control effectiveness.
