基于解耦优化和环流APF的多平台协同攻击任务规划

为提升协同攻击任务规划效率，借助人工势场（APF）方法求解速度快的优势，提出多平台协同攻击任务规划方法。针对任务规划问题中任务分配与航路规划的耦合问题，提出基于独立航路规划的解耦（ID）与基于直接距离的解耦（DD）2种解耦框架；建立考虑打击目标价值总和、攻击平台与目标距离极差、攻击平台与目标距离总和等因素的指标函数，采用遗传算法进行任务分配求解；提出环流APF方法，避免了传统APF方法因局部极小值而无解的问题，并提出同时到达控制策略与航路冲突规避策略，实现多平台同时到达航路规划。在不同场景下比较了耦合方式、ID、DD 3种任务规划框架的规划结果，并对比了传统APF方法与环流APF方法的航路规划结果。结果表明，解耦方式能够得到与耦合方式接近的结果，并且计算耗时明显低于耦合方式；环流APF方法相比传统APF方法求解可行性更高，航路性能更好。对于存在大块障碍的场景，推荐使用ID方式获得更好的准确度，在障碍稀疏的场景下，推荐使用DD方式以减少计算耗时。 

Multi-platform cooperative task planning with decoupling optimization and circulating APF

For better performance in cooperative task planning, a multi-platform task planning method is proposed with the high efficient Artificial Potential Field (APF) method. For the coupling problem of task assignment and path planning in task planning, two decoupling frameworks are presented, namely Decoupling with Independent path planning (ID) and Decoupling with Direct distance (DD). The objective function of task assignment is constructed considering the sum of target value, range of distance between platform and target, and sum of distance between platform and target, and is solved with genetic algorithm. By presenting circulating APF, the no-solution problem of traditional APF method caused by local-minima is avoided, and the simultaneous arrival control strategy and path confliction avoidance strategy are proposed for path planning of multi-platform simultaneous arrival. The simulation is conducted in different scenarios with coupling method, ID and DD. And the path planning results of traditional APF and circulating APF method are also compared. The results suggest that, decoupling methods can reach results close to coupling method but with less time cost than coupling method. And compared with traditional APF method, circulating APF method is characterized with better solution feasibility and path performance. For method application, it is recommended that ID method is used in big block obstacle scenarios for better precision, and DD method is used in sparse obstacle scenarios for better efficiency.
