IMPACT TIME CONTROL GUIDANCE METHOD AND DEVICE

摘要

Disclosed are a collision time control guidance method and a system thereof. According to an embodiment of the present invention, a collision time control guidance system includes: a time constraint condition acquisition unit which acquires collision time information indicating the time that a gas is supposed to reach a target as time constraint conditions; a target information acquisition unit which acquires target information related to the location of the target that the gas is supposed to reach; a candidate function setting unit which uses a collision time error obtained from the relationship with the time constraint conditions obtained by the time constraint condition acquisition unit to set a Lyapunov candidate function; an acceleration command generation unit which uses the Lyapunov candidate function set by the candidate function setting unit to generate an acceleration command normalized to velocity of the gas in consideration of a motion equation in a coordinate system having the gas and the target arranged therein; and a flight control unit which controls the flight of the gas in accordance with the acceleration command.
