AIRCRAFT POSITION CONTROL SYSTEM, AIRCRAFT, AND AIRCRAFT POSITION CONTROL METHOD

摘要

According to the present invention, an aircraft is moved to a target landing point more accurately and quickly. This aircraft position control system comprises: a relative position acquisition unit which acquires the relative position between an aircraft and a target landing point; a relative velocity acquisition unit which acquires the 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 of the aircraft by feedback control such that the aircraft heads for the target landing point, on the basis of at least the relative position and the relative velocity, a multi-value control unit which, on a coordinate plane with the relative position and 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 the coordinate points of the current 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 for calculating an aircraft control amount obtained by adding the additional value to the feedback control amount.
