To more accurately and quickly move an aircraft toward a target landing point.SOLUTION: A position control system comprises: a relative position acquisition unit which acquires a relative position between an aircraft and a target landing point; a relative velocity acquisition unit which acquires relative velocity of the aircraft with respect to the target landing point; and a control unit which controls the aircraft. The control unit includes: a feedback control unit which calculates a feedback control amount such that the aircraft heads for the target landing point; a multi-value control unit which, on a coordinate plane with the relative position and the relative velocity as orthogonal axes, a switching line is set in advance that passes through an origin and separates an acceleration region in which the relative velocity is increased and a deceleration region in which the relative velocity is decreased, sets an additional value that tends to increase the relative velocity when coordinate points of the relative position and the relative velocity are located in the acceleration region, and sets an additional value that tends to decrease the relative velocity when the coordinate points are located in the deceleration region with respect to the switching line; and an addition circuit which calculates an aircraft control amount obtained by adding the additional value to the feedback control amount.SELECTED DRAWING: Figure 8
【課題】航空機を目標着地点に向けて、より精度良く、かつ、速やかに移動させる。【解決手段】位置制御システムは、航空機と目標着地点との相対位置を取得する相対位置取得部と、目標着地点に対する航空機の相対速度を取得する相対速度取得部と、航空機を制御する制御部と、を備える。制御部は、航空機が目標着地点に向かうように、フィードバック制御量を算出するフィードバック制御部と、相対位置および相対速度を直交軸とする座標平面上で、原点を通り、相対速度を増加させる増速領域と相対速度を減少させる減速領域とを区分けする切替線が予め設定され、相対位置および相対速度の座標点が増速領域に位置するとき、相対速度が増加する傾向の加算値を設定し、切替線に対して、座標点が減速領域に位置するとき、相対速度が減少する傾向の加算値を設定する多値制御部と、フィードバック制御量に加算値を加算した航空機の制御量を算出する加算回路と、を備える。【選択図】図8
