【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。
[Abstract]:Aiming at the standard trajectory tracking problem of hypersonic glider under the condition of large deviation, a new tracking guidance method based on weight matrix adaptive correction is proposed. The main control methods and standard trajectory characteristics are analyzed. The simplified longitudinal motion equation is linearized near the standard trajectory, the error term is introduced into the weighted matrix of linear quadratic performance index, and an improved weight adaptive modified tracking guidance method is designed. The simulation analysis of CAV-H vehicle shows that, This method can realize the high-precision adaptive tracking guidance of hypersonic glider in the orbit changing section, and has good robustness to the initial and process deviations.
