摘　　要：针对高超声速滑翔飞行器变轨段大偏差条件下的标准轨迹跟踪问题,提出一种基于权值矩阵自适应修正的变轨段跟踪制导方法。分析了变轨段主要控制方式和标准轨迹特性;将简化的纵向运动方程在标准轨迹附近线性化;采用将误差项引进线性二次型性能指标加权矩阵的方式,设计了改进的权值自适应修正跟踪制导方法。CAV-H飞行器仿真分析表明,该方法能够实现高超声速滑翔飞行器变轨段高精度自适应跟踪制导,对初始及过程偏差具有良好的鲁棒性。According to the trajectory tracking problem of hypersonic glide vehicle under great deviation conditions, a new adaptive tracking guidance method in the injection phase was put forward based on the adaptively revised weighting matrix. The main control mode and standard trajectory characteristics were analyzed. The simplified longitudinal motion equations were linearized near the standard trajectory. An improved adaptive tracking guidance method was designed by introducing the error term in linear quadratic performance index. The simulation results of CAV Hindicate that this method can achieve a great performance in adaptive tracking guidance in the injection phase, and has a good robustness to the initial and process deviation.
