PROBLEM TO BE SOLVED: To provide a motion exercise device capable of supporting a plane motion of a user comfortably.SOLUTION: A motion exercise device includes: an operation unit 3 that can be moved on an XY plane; an actuator mechanism having X-axis and Y-axis direction drive motors for driving the operation unit 3 on the XY plane; a force sensor for detecting X-axis and Y-axis direction force that acts on the operation unit 3; and a control unit for calculating speeds of the operation unit 3 in X-axis and Y-axis directions based on the X-axis and Y-axis direction force detected by the force sensor, and controlling the X-axis and Y-axis direction drive motors according to the calculated speeds. The control unit controls at least one of the X-axis and Y-axis direction drive motors in a control mode of PD control or P control.SELECTED DRAWING: Figure 13COPYRIGHT: (C)2020,JPO&INPIT【課題】使用者による平面運動を快適に支援可能な運動訓練装置を提供する。【解決手段】運動訓練装置は、XY平面で移動可能な操作部3と、X軸およびY軸方向駆動モータを有し操作部3をXY平面で駆動するアクチュエータ機構と、操作部3に作用するX軸およびY軸方向の力を検出する力センサと、力センサで検出されたX軸およびY軸方向の力に基づいて操作部3のX軸およびY軸方向の速度を算出し、該算出した速度に応じてX軸およびY軸方向駆動モータを制御する制御部とを備えている。制御部は、X軸およびY軸方向駆動モータの少なくとも一方をPD制御またはP制御の制御モードで制御する。【選択図】図13
