摘要:

提出了一种基于随机最优控制理论的无人机编队控制方法。该方法包括一个集中的高层次的计划,计算最佳状态轨迹的速度序列,和一个特定于平台的低层次的控制器,确保这些速度序列得到满足。规划任务表示为一个集中式路径积分控制问题,最优控制计算对应于一个概率推理问题,可以解决有效的采样方法。通过仿真,我们表明,我们的SOC方法(a)具有显着的好处相比,确定性控制和其他SOC方法在多模态问题与噪声相关的最佳解决方案,(b)是能够控制大量的平台实时,(c)产生集体紧急行为的形式的飞行编队。最后,我们表明,我们的方法适用于真实的平台,通过控制一个团队的三个四旋翼在户外条件下。

英文摘要:

This paper presents a novel method for controlling teams of unmanned aerial vehicles using Stochastic Optimal Control (SOC) theory. The approach consists of a centralized high-level planner that computes optimal state trajectories as velocity sequences, and a platform-specific low-level controller which ensures that these velocity sequences are met. The planning task is expressed as a centralized path-integral control problem, for which optimal control computation corresponds to a probabilistic inference problem that can be solved by efficient sampling methods. Through simulation we show that our SOC approach (a) has significant benefits compared to deterministic control and other SOC methods in multimodal problems with noise-dependent optimal solutions, (b) is capable of controlling a large number of platforms in real-time, and (c) yields collective emergent behaviour in the form of flight formations. Finally, we show that our approach works for real platforms, by controlling a team of three quadrotors in outdoor conditions.
