摘　　要：为了应对小行星撞击的风险,需要研究有效的在轨处置技术手段。目前,国际公认的最为有效的在轨处置手段为动能撞击。为了能够满足撞击的有效性,需要确保撞击器在高撞击速度下的高精度制导控制。本文针对未来小行星在轨处置的末段高精度制导控制任务需求,基于光学惯性复合导航,设计了像平面纠偏比例导引方法,并进行了数学仿真。仿真实验结果表明:像平面纠偏比例导引方法能够满足末端的高速、高精度制导控制需求,并能够适应给定的不同误差组合。该方法同时具备计算量小、无迭代不收敛问题等优势,具有较强的工程实用价值。To deal with the risk of asteroid impacts,effective on-orbit disposal means need to be studied.The most effective on-orbit disposal way which is well recognized internationally is kinetic impact.In order to achieve the effective impact to the asteroid,it is necessary to ensure high precision guidance and control for the impactor at high relative velovity.This paper developed a deviation of image plane rectified proportional guidance method based on optical inertial integrated navigation for the requirements of the terminal high precision guidance and control in the future asteroid on-orbit disposal mission.And some mathematical simulations are made to verify the performance of the method.The simulation results show that the deviation of image plane rectified proportional guidance meth-od can meet the requirements of the terminal high precision guidance and control at high relative velocity condition,and it can adapt to different error combinations given.This method has the advantages of low calculation cost and no risk of non-converge in iteration,and has strong engineering practical value.
