摘　　要：针对智能优化算法在求解无人机三维航迹规划问题时存在搜索能力不足、收敛速度慢和易陷入局部最优等问题,提出了一种鱼鹰搜索策略蛇优化(OSSO)算法。首先,引入Bernoulli混沌映射初始化种群,扩大个体搜索范围,丰富种群的多样性;其次,结合鱼鹰优化算法下潜捕食、随机步长和精确开采思想,改进算法搜索策略,增强其全局搜索能力;然后,通过动态折射反向学习策略进行种群更新,提升算法对局部极值的处理能力,平衡算法全局搜索和局部开采能力;最后,分别采用函数法和高程数据构建2种三维模型,将航迹长度、威胁区距离和无人机本体约束作为评判指标进行仿真实验。实验结果表明:OSSO算法具有较强的鲁棒性,对于求解三维航迹规划问题具有良好的稳定性和有效性。Aimed at the problems that search ability is inadequate in search,convergence is slow at speed,and susceptible to local optima in the intelligent optimization algorithm for solving the UAV 3D flight planning problem,an Osprey Strategy Snake Optimizer(OSSO)is proposed.Firstly,Bernoulli chaotic mapping is introduced to initialize the population,expand the individual search range,and enrich the diversity of the population;Secondly,the search strategy is improved in combination with the ideas of submerged predations,stochastic step and precise mining in the Osprey Strategy Snake Optimizer,and the global search capability is enhanced;And then,the dynamic opposition-based learning is utilized for updating population,balancing the algorithm’s global exploration and local mined ability,and improving the algorithm’s ability to deal with local optima.Finally,two 3D models are constructed by the function method and elevation data respectively,and the simulation experiment is performed by taking the length of trajectory,the distance in threat zone and the drone physical constraints as the judging indexes.The experimental results show that the OSSO algorithm is rugged,and good in stability and in effectiveness in solving the three-dimensional track planning problems.
