AI总结:

针对范围内跟踪任务,本文提出覆盖始终在域与允许离域两类情形的最优控制公式化及正则化方法,并扩展到多跟踪器和高维场景,显著延长任务持续时间。

摘要:

与旨在减小跟踪器与参考值之间跟踪误差的设定点跟踪不同,范围内跟踪问题仅关注跟踪器是否处于参考值周围的给定范围内,因此更适合许多实际应用的任务规范。在本工作中,我们提出了用于求解范围内跟踪问题的新型最优控制公式化方法,既涵盖要求跟踪器始终处于范围内的问题,也涵盖允许跟踪器离开范围以获得整体更优结果的问题。由于该问题天然涉及不连续函数,我们提出了替代公式化方法和正则化策略,以提升数值求解器的性能。文中还讨论了向多跟踪器范围内跟踪以及高维空间中范围内跟踪的扩展,并通过数值示例加以说明,结果表明,与传统设定点跟踪相比,任务持续时间得到了显著增加。

英文摘要:

In contrast to set-point tracking which aims to reduce the tracking error between the tracker and the reference, tracking-in-range problems only focus on whether the tracker is within a given range around the reference, making it more suitable for the mission specifications of many practical applications. In this work, we present novel optimal control formulations to solve tracking-in-range problems, for both problems requiring the tracker to be always in range, and problems allowing the tracker to go out of range to yield overall better outcomes. As the problem naturally involves discontinuous functions, we present alternative formulations and regularisation strategies to improve the performance of numerical solvers. The extension to in-range tracking with multiple trackers and in-range tracking in high dimensional space are also discussed and illustrated with numerical examples, demonstrating substantial increases in mission duration in comparison to traditional set-point tracking.
