摘要
针对应急抢险船舶在极端洪涝灾害时的路径规划问题,提出一种改进人工势场法的路径规划算法,实现内河应急抢险船舶的快速精准救援。由于传统人工势场法中存在局部极小点、目标不可达等影响应急抢险船舶救援的安全问题,通过改进斥力势场函数解决了船舶在靠近障碍物的救援点时的目标不可达问题;引入逃逸力避免了局部极小点问题。通过数值仿真试验对比验证,改进后的人工势场法能够帮助应急抢险船舶在复杂的内河航道环境中安全到达救援点。
Aiming at the path planning problem of emergency rescue vessels during extreme flooding,a path planning algorithm with improved artificial potential field method is proposed to achieve fast and accurate rescue of inland river emergency rescue vessels.Due to the safety problems such as local minimum point and unreachable target in the traditional artificial potential field method,the repulsion potential field function is improved to solve the unreachable target problem when an emergency rescue vessel is close to the rescue point of an obstacle.Through numerical simulation experiments,the improved artificial potential field method can help emergency rescue vessels safely reach the rescue point in complex inland waterway environments.
