针对多约束条件下高超声速滑翔飞行器滑翔段再入制导问题，提出一种改进的预测-校正制导方法。该方法基于模型预测静态规划（MPSP），将三维轨迹快速在线生成方法作为初值生成器，解决了MPSP制导方法提供猜测值困难、对于初始偏差需要重新计算参考轨迹的问题。建立了基于能量的运动学模型，推导了MPSP预测-校正制导律。探讨了初始下降段对滑翔段的影响因素，针对滑翔段初值干扰和气动参数摄动问题，进行了数字仿真。仿真结果表明，改进的MPSP预测-校正制导方法能够有效利用精确的猜测值，提高了计算效率，对干扰初值和气动摄动具有较强的鲁棒性。

Aiming at the reentry guidance of hypersonic gliding vehicle considering multi-constraints,the research proposes an improved predictor-corrector guidance law,which is based on model predictive static programming(MPSP).The initial value generator was founded by using the rapid generation of three dimensional trajectory,which solves the MPSP problem of providing guess history difficultly and refreshing nominal trajectory for the initial perturbation.The kinematic model of the hypersonic gliding vehicle was built based on energy,and the predictor-corrector guidance based on MPSP was deduced.The influence factors from the initial decent phase to the gliding phase were investigated.The digital simulation was carried out in gliding phase considering perturbations of the initial values and aerodynamic parameters.The results turn out that the improved MPSP predictor-corrector method have the advantages of precise initial guess values,computational efficiency and strong robustness to the perturbations.
