基于改进蚁群算法的移动机器人路径规划OA
Mobile robots path planning based on improved ant colony algorithm
移动机器人路径规划是机器人的重要研究领域之一,根据机器人接收的任务和周围环境信息,为其寻找一条从起点到终点且没有碰撞的最优路径.针对蚁群算法存在的收敛速度慢、路径繁冗及易陷入局部最优等问题,本文提出了一种改进的蚁群算法.首先,通过融合具有目标导向性的Euclidean距离与Chebyshev距离以提高蚂蚁前期的搜索效率,并在启发函数中引入正态分布来提高路径的搜索精度;其次,在信息素更新机制中加入奖惩策略,通过强化优秀路径引导能力以提高算法收敛速度;然后,结合自适应信息素挥发因子动态调节搜索行为,增强全局寻优能力,降低陷入局部极值的风险;最后,通过剪枝操作,减少机器人转弯次数,缩短路径距离.通过在二维和三维环境中与其他算法进行仿真对比实验,结果表明,改进算法不仅能够找到最短路径,而且在运行时间上也表现出更高的搜索效率.
Path planning for mobile robots is considered one of the fundamental research areas in robotics.It involves determining an optimal,collision-free path from a start point to a target based on the assigned task and environmental perception.To address the limitations of the standard ant colony optimization(ACO)algorithm,including slow conver-gence,redundant paths,and susceptibility to local optima,this study proposes an improved ACO algorithm.Firstly,goal-oriented Euclidean and Chebyshev distances are fused to enhance early-stage search efficiency,and a normal distribution(Gaussian distribution)is introduced into the heuristic function to improve path search precision.Secondly,a reward-penalty strategy is incorporated into the pheromone update mechanism to reinforce the influence of high-quality paths and accelerate convergence.Thirdly,an adaptive pheromone evaporation factor is applied to dynamically adjust the search behavior,thereby enhancing global exploration and reducing the risk of becoming trapped in local op-tima.Finally,a pruning strategy is employed to reduce the number of turns and shorten the overall path length.Com-parative simulation experiments with other algorithms in both two-dimensional and three-dimensional environments demonstrate that the proposed algorithm not only yields shorter paths but also exhibits higher search efficiency in terms of running time.
