| 摘 要： | 为了提高现有航迹规划系统的实时规划能力,对基于分层策略的航迹规划方法中全局规划部分进行改进,提出了基于病毒遗传算法的快速规划方法.分层策略的航迹规划包括全局规划和局部规划,由于对不同性质的约束条件分阶段进行处理,该方法降低了航迹规划的计算复杂度.但全局规划采用的标准遗传算法仍存在早熟和局部收敛慢的问题.针对这些缺陷,采用病毒遗传算法进行改进.结合航迹规划的领域知识,给出了病毒种群的编码方法并设计了特定的病毒感染算子,使航迹寻优效率得以提高.仿真实验表明,在相同约束条件下,该方法能更快生成满足战术要求的航迹.

| Abstract: | To enhance the real time planning ability of existing system,a fast path planning method based on virus-evolutionary genetic algorithm is proposed,the proposed method is aimed at improving the global step of a path planning method based on hierarchical strategy.The hierarchical planning method is used to efficiently handle path constraints by dividing the whole planning process into two steps: global planning and local planning.Employing a hierarchical strategy,this method may reduce the computation complex... |
