Abstract
An aircraft position control system that keeps an aircraft at target coordinates in an inertial space with respect to a target landing point that moves includes an acceleration correction processing unit that, based on acceleration of the aircraft and an attitude of the aircraft, outputs first attitude correction acceleration for correcting the acceleration of the aircraft, a complementary filter that, based on the first attitude correction acceleration and inertial velocity of the aircraft, outputs second attitude correction acceleration in which a drift component included in the first attitude correction acceleration is removed, and a smoothing processing unit that, based on the second attitude correction acceleration and relative coordinates between the aircraft and the target landing point, outputs smoothed relative coordinates obtained by smoothing the relative coordinates.
