Control Performance of Hadamard-Weighted H² Controller for Multiple-Input Structure System

In this study, a design method of a controller taking account of integrity is presented using Hadamard weighted H² control theory. Numerical calculations are carried out by using a structure model with an active dynamic vibration absorber (ADVA) and an active vibration isolator (AISO). It is shown that the controller designed by using the proposed method realizes higher integrity than the ordinary weighted H² controller, though it requires more amount of control inputs to achieve same vibration reduction effect in average.
