To provide an actuator device which can precisely control a position of a mobile body, i.e., an object even if a weight of the object is changed while the actuator apparatus is used.SOLUTION: An actuator apparatus 100 has a moving body for supporting an object 3, a supporting mechanism for supporting the moving body so that the moving body can be lifted upward and downward, and a control system 16 for controlling an operation of the supporting mechanism. The supporting mechanism includes first and second force application means for applying upward and downward force to the moving body. The control system 16 has a first control unit 64 for controlling the first fore application means so that a force required for the moving body to follow a target position can be applied to the moving body, a second control unit 66 for controlling the second force application means so that a force required to support the moving body and the object can be applied to the moving body, and acquiring means for acquiring information regarding weight of the object in response to the target position. The second control unit 66 controls the second force application means, when the weight of the object is changed, so that the change can be compensated for.SELECTED DRAWING: Figure 1

    【課題】使用中に対象物の重量が変化する場合でも、移動体ひいては対象物の位置を的確に制御できるアクチュエータ装置を提供する。【解決手段】アクチュエータ装置100は、対象物3を支持する移動体と、移動体を昇降可能に支持する支持機構と、支持機構の動作を制御する制御システム16と、を備える。支持機構は、移動体に昇降方向の力を付与する第1、第2力付与手段を含む。制御システム16は、移動体が目標位置に追従するための力を移動体に付与するよう第1力付与手段を制御する第1制御部64と、移動体および対象物を支持するための力を移動体に付与するよう第2力付与手段を制御する第2制御部66と、目標位置に応じた対象物の重量に関する情報を取得する取得手段と、を含む。第2制御部66は、対象物の重量が変化した場合、その変化を補償するように第2力付与手段を制御する。【選択図】図1
