    摘要:

    针对机器人战术靶在实际战术演练中需实现任意路径的跟踪控制,提出一种示教路径采样和跟踪控制策 略。基于2 种示教分别制定路径点采样策略,其中:在线示教人工远程操作机器人战术靶行走,构建基于行驶距离 和转弯半径的路径点采样策略;离线示教通过上位机在地图文件上编辑定义一系列离散的路径点来完成示教路径的 绘制。路径再现阶段读取之前存储的示教路径,采用节点跟踪切换控制策略、速度分段控制策略、基于航向和偏距 组合误差的方向控制策略来控制机器人对路径的跟踪。在物理样机上对算法进行验证,结果表明:机器人战术靶可 很好地对任意复杂示教路径进行跟踪,其中路径跟踪偏差小于0.3 m,各路径点到点跟踪速度偏差小于5%。

    Abstract:

    In order to realize the tracking control of arbitrary path in the actual tactical exercise of robot tactical target, a strategy of teaching path sampling and tracking control is proposed. The path point sampling strategy is established based on the 2 teaching methods, in which the path point sampling strategy based on the driving distance and turning radius is established for the online teaching of manual remote operation of robot tactical target walking, and the teaching path is drawn by editing and defining a series of discrete path points on the map file through the host computer for offline teaching. In the path reproduction stage, the taught path stored before is read, and the path tracking of the robot is controlled by using a node tracking switching control strategy, a speed segmentation control strategy and a direction control strategy based on a heading and offset combined error. The algorithm is verified on the physical prototype, and the results show that the robot tactical target can track any complex teaching path well, in which the path tracking deviation is less than 0.3 m, and the point-to-point tracking speed deviation of each path is less than 5%.
