Position control system for vertical takeoff and landing aircraft, vertical takeoff and landing aircraft, and position control method for vertical takeoff and landing aircraft

A position control system for a vertical takeoff and landing aircraft, the system comprising:

• a relative speed acquisition unit that acquires a relative speed based on a relative position between a vertical takeoff and landing aircraft and a landing target point;
• a relative altitude acquisition unit that acquires a relative altitude based on the relative position between the vertical takeoff and landing aircraft and the landing target point;
• a swaying amount estimation processing unit that estimates a swaying amount of the landing target point based on the relative altitude and a vertical acceleration of the vertical takeoff and landing aircraft;
• and
• a target information generation unit that calculates a target relative altitude as a target between the vertical takeoff and landing aircraft and the landing target point based on the swaying amount.

A position control method for a vertical takeoff and landing aircraft, the method comprising:

• a step of acquiring a relative speed based on a relative position between a vertical takeoff and landing aircraft and a landing target point;
• a step of acquiring a relative altitude based on the relative position between the vertical takeoff and landing aircraft and the landing target point;
• and
• a step of determining whether contact occurs between the vertical takeoff and landing aircraft and the landing target point based on the relative speed and the relative altitude.
