移动机器人动态人工势场路径规划方法研究

针对传统人工势场法在多障碍物环境中进行路径规划存在局部极小值,以及动态环境中移动机器人无法实时路径规划等问题,提出一种动态模糊控制的改进人工势场法,通过在势场力函数中引入速度矢量项,并采用模糊控制方法实时调节斥力场系数,从而实现在动态多障碍物的环境下机器人快速、实时、自适应的路径规划.仿真结果表明,该方法有效可行,在典型位置关系及特殊运动状态下均可获得良好的路径规划性能.

Abstract：

For traditional artificial potential field (APF) method,the local minima problem exists and can not satisfy the requirement of real-time for path planning of mobile robots in the multi-obstacle dynamic environment. A new APF method based on dynamic fuzzy control is proposed in this paper. The potential field force function is modified by introducing the velocity vector. The coefficients of potential field of repulsive force are adjusted by fuzzy control method. A fast real-time self-adaptive path planning method with dynamic multi-obstacle is realized. The simulation results show that the method is effective and feasible, and can get much better performance of path planning in typical location relationship and special motion relationship.
