目标机动补偿的动能拦截器增量式制导方法

In view of the design problem of a strong anti-disturbance terminal guidance method for kinetic kill vehicles against highly maneuvering targets, thrust disturbance, and measurement deviation, an incremental strong anti-disturbance terminal guidance method for extra-atmospheric kinetic kill vehicles with target maneuver compensation is proposed. By exploiting the thrust sensing information and the auxiliary differential information of the line-of-sight rate and combining the incremental guidance law and the inertial time delay-based disturbance estimation method, the disturbance caused by the uncertainties brought by target maneuvers and the internal and external uncertainties was compensated in real time and integrated into the guidance algorithm, so as to degrade the disturbance and enhance the robustness of the kinetic kill vehicle's guidance system against maneuvering targets under complex working conditions. The simulation results under complex working conditions show that the proposed method has strong anti-disturbance capability against multi-source disturbances such as highly maneuvering targets, measurement deviations, and thrust disturbance and thus can fulfill interception tasks by precise collision.
