Collision avoidance path planning of carrier aircraft traction system in dispatching on deck

针对舰载机牵引系统的甲板调运过程,提出了一种适用于复杂障碍物环境中不规则形状目标的路径规划方法。针对舰载机外轮廓特点,建立了目标的凸构型描述形式,并推导了多目标间碰撞检测及距离计算方法,在此基础上提出了舰载机牵连运动的轨迹跟踪控制算法,同时引入行为动力学方法实现牵引系统的避碰路径规划。为提高复杂环境下的避碰能力,基于广义符号阈值函数,提出了避障行为策略改进方法。仿真结果表明,本文提出的算法能够有效地解决舰载机牵引系统的避碰路径规划问题。

For dealing with dispatching of the carrier aircraft tractor system on deck,a path planning meth-od applicable to the objective of irregular shape in a complex environment with obstacles is described.Considering the features of the carrier-based aircraft outline whose convex polygon description is given,the involved collision de-tection and distance calculation are performed.A trajectory tracking control algorithm for carrier aircraft trac-tion motion is then proposed,meanwhile collision avoidance path planning is realized through conventional be-havior dynamics.In order to raise the collision avoidance ability in complicated environment,based on the gener-alized symbolic threshold function,the obstacle avoidance behavior strategy is improved.In the simulation,the path planning problems with respect to the carrier aircraft tractor system is effectively solved using the algo-rithm developed.
