摘要:

本文提出了一种新颖且高效的基于优化的方法,用于生成在复杂但结构化的环境中运行的全向车辆的近时间最优轨迹。该方法旨在利用磁悬浮技术解决平面运动系统的运动规划问题,该技术可用于装配线、自动化实验室或洁净室。在这些应用中,需要能够实时计算的时间最优轨迹以提高生产率,并在需要时使车辆具有反应能力。所提出的方法通过自由空间走廊编码环境表示,并通过此类走廊表示车辆运动使用运动原语。这些原语是启发式选择的,并通过有限数量的自由度定义轨迹,这些自由度在优化问题中确定。因此,该方法在计算时间上显著低于最先进的方法,特别是解决完整的最优控制问题(OCP)、OMG-tools或VP-STO,而不会显著牺牲最优性。该方法在模拟中进行了广泛测试,并在现实中的Beckhoff XPlanar系统上进行了验证。

英文摘要:

This paper proposes a novel and efficient optimization-based method for generating near time-optimal trajectories for holonomic vehicles navigating through complex but structured environments. The approach aims to solve the problem of motion planning for planar motion systems using magnetic levitation that can be used in assembly lines, automated laboratories or clean-rooms. In these applications, time-optimal trajectories that can be computed in real-time are required to increase productivity and allow the vehicles to be reactive if needed. The presented approach encodes the environment representation using free-space corridors and represents the motion of the vehicle through such a corridor using a motion primitive. These primitives are selected heuristically and define the trajectory with a limited number of degrees of freedom, which are determined in an optimization problem. As a result, the method achieves significantly lower computation times compared to the state-of-the-art, most notably solving a full Optimal Control Problem (OCP), OMG-tools or VP-STO without significantly compromising optimality within a fixed corridor sequence. The approach is benchmarked extensively in simulation and is validated on a real-world Beckhoff XPlanar system
