再入滑翔式飞行器轨迹快速优化

为了满足再入滑翔飞行器轨迹实时生成的要求,提出了一种轨迹快速优化方法.在模型处理方面,根据再入飞行器运动的特点,对再入轨迹方程进行了合理的简化处理和无量纲化处理,使其更适合数值优化算法求解;在算法方面,采用乘子法对再入终端约束进行处理,然后采用共轭梯度法求解最优的再入轨迹.仿真结果表明,这样处理只需10s左右的时间便能产生一条满足约束条件的再入优化轨迹,验证了模型

Fast Trajectory Optimization of Reentry Gliding Vehicle

In order to generate the optimal solutions of trajectories for reentry gliding vehicle in real time,this paper presents a kind of fast trajectory optimization method.When disposing the model,according to the characteristics of reentry vehicle,the reentry motion equations are simplified based on some reasonable assumptions and the equations are transformed into non-dimensional form,to make it more suitable to be solved by the numerical optimal algorithms.Then the methods of multipliers are used to deal with ...
