ハイブリッド式建設機械旋回システムの開発 : 第1報,旋回用電動機の制御方法に関する検討(機械力学,計測,自動制御)

Recently, in the viewpoint of environment problems, the improvement of the efficiency of the construction machinery such as excavator or crane is demanded. For this purpose, it is investigated that the hybrid system used in the automobile is adapted into the construction machinery. The one of the problems in this development is that the operating property of the system needs to be close to the present hydraulic construction machinery. Therefore this study focused on the swing system of the hybrid construction machinery and proposed the control method to derive the operating property that is close to the present hydraulic construction machinery. The effect of this control method is confirmed by experiment.
