In the active vibration control, it is important that the control system be robust against mass variation of the car body due to the varying number of passengers. However, it was indicated that LQG controller can become unstable when the body mass is lightened. Although H_\u221e controller is stable against the mass variation, it is expected that the adoption of \u03bc synthesis can improve the control performance still more. In this paper, the car body mass variation is considered in the linear state space representation of control object as parametric uncertainty, so that the \u03bc synthesis can be adopted for the controller design. The control performance of the \u03bc controller is investigated with a 3 d. o. f. half-vehicle model experimentally. As a result, it is shown that the \u03bc controller improves the deterioration due to the car body mass reduction, and that it provides better control performance using a frequency dependent weighting function more than using constant weightings for the uncertainty of the mass variation.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name":
