摘要
为解决弹载计算机内存小、运算速度慢与在线航迹规划内存需求大、实时性要求高之间的矛盾,给出了基于高速DSP的高超声速飞行器在线航迹规划方案。介绍了一种实时航迹规划策略,设计了基于ADSP21364的在线航迹规划器,提出了改进的稀疏A*算法,最后进行了地面模拟飞行试验。仿真结果表明,设计的规划策略和规划算法能够在现有硬件基础上避开各种新威胁,生成一条当前最优/次优的航迹,并且规划稳定性好、成功率高。
In order to improve the efficiency and stability of the route planning for hypersonic cruise vehicle, this paper proposes an approach using improved spares A* algorithm with variable steps based on the DSP and designs a hypersonic vehicle on--line route planning system with ADSP--21364, which can generate on--line trajectory based on off--line route when new threats appear, The results of flight simulation experiments demonstrate that the planning strategy and improved A* algorithm can save plenty of memory and decrease the com- plexity of planning algorithm, further more, the re--planned route can dodge all kinds of new threats and satisfy all the flight demands for on --line route planning.
