| 摘要:本研究引入了一种融合A*与DWA算法的叉车式自动引导车(AGV)混合导航算法,并基于Bezier曲线优化全局规划路径,同时采用改进适应度函数、引入动态惯性权重因子等方法进行优化,以适用于造纸生产车间等复杂室内场景下的路径规划与局部避障。结果表明,相较于传统A*算法,Bezier优化的改进A*算法下的叉车式AGV轨迹缩短了3.4 m,显著提高了叉车式AGV工作效率(轨迹效率提升7.26%),且导航轨迹曲线更平滑,具有更高的可靠性。此外,经过实验验证,融合A*与DWA算法的叉车式AGV混合导航算法具有较好的全局最优性和局部避障能力。 |
| Abstract:This study introduced a hybrid navigation algorithm for forklift-type automated guided vehicle (AGV) that integrated the A* and DWA algorithms. It optimized the global planning path based on Bezier curves and employed methods such as an improved fitness function and the introduction of a dynamic inertia weight factor for further optimization. This approach enabled effective path planning and local obstacle avoidance methods in complex indoor scenarios, such as paper manufacturing workshops. The results indicated that, compared to the traditional A* algorithm, the trajectory of the forklift-type AGV optimized by Bezier reduced 3.4 m, significantly enhancing the work efficiency of the forklift-type AGV (with a trajectory efficiency increase of 7.26%). Furthermore, the navigation trajectory curve exhibited smoother operation and higher reliability. Additionally, the hybrid navigation algorithm for forklift-type AGV, which integrated A* and DWA algorithms, had been verified through experiments to possess superior global optimality and local obstacle avoidance capabilities. |
