MR ダンパーの最適制御によるセミアクティブ制御効果の評価

－システム特性評価とパラメータ設定法－

抄録

This study elucidates a method to ascertain control variables such as the performance function and weight coefficient, at the initial stage of structural design. For the purpose, authors assess the structural properties (equivalent damping factor and equivalent natural circular frequency) of semi-active optimal control system by MR damper to evaluate the structure response. First, the relations between weight coefficient and those system properties are discussed. Secondly, control parameter determination in consideration in the maximum controlling force is proposed. Validity of those design proposals are investigated by real-time hybrid experiments and numerical simulations.
