1. An aircraft control system comprising:
a target instruction value calculation unit configured to acquire a target instruction value to set an aircraft in a target state;
a reference velocity calculation unit configured to input, to a reference model in which a reference velocity corresponding to a reference value of an aircraft velocity is set uniquely as an output value in accordance with an input value, a value based on the target instruction value as the input value, to calculate the reference velocity;
a relative velocity calculation unit configured to calculate a relative velocity of the aircraft to a target position, the relative velocity being for control of the aircraft;
an estimated disturbance quantity calculation unit configured to calculate an estimated disturbance quantity acting on the aircraft, based on a difference between the relative velocity and the reference velocity;
a correction target instruction value calculation unit configured to correct the target instruction value based on the estimated disturbance quantity calculated at a previous time; and
a flight control unit configured to perform flight control of the aircraft according to a correction target instruction value that is the corrected target instruction value.
