'''What we did'''
 * We made damping filters for horizontal (L, T, Y) in order to damp the resonant peak around 1 Hz.
 * As a result, the damping filter worked and the resonant peaks were damped.
 * However, there was problem.
 * ダンピングフィルターを作成してL,T,Yそれぞれ１つずつ（1度に1つの自由度のみに対して）フィルターを適用したところ、ダンピングが働いてピークが消えた。一方で、３つ同時にフィルターをかませると、うまくダンピングできずにピークが残ってしまった。

  • However, there was problem.
  • ダンピングフィルターを作成してL,T,Yそれぞれ１つずつ（1度に1つの自由度のみに対して）フィルターを適用したところ、ダンピングが働いてピークが消えた。一方で、３つ同時にフィルターをかませると、うまくダンピングできずにピークが残ってしまった。
