摘要:

本文建立了一个将局部可控性、最优性必要条件和自由时间最优控制问题中可达性联系起来的统一框架。我们研究的核心对象是Λ集,它决定了原始控制系统与其凸化之间的关系。我们的主要结果表明,Λ集的空集性意味着局部可控性,并保证了在减少时间内达到目标的最小化序列的存在。我们推导了时间最优控制的加强必要条件,并提供了用普通轨迹近似广义控制的显式构造程序。这些结果解决了长期存在的松弛现象问题,同时将经典理论扩展到非凸优化的现代挑战,为自由时间问题中的更高阶分析奠定了基础。

英文摘要:

This paper establishes a unified framework connecting local controllability, necessary conditions for optimality, and attainability in free-time optimal control problems. The central object of our investigation is the $Λ$-set, which governs the relationship between original control systems and their convexifications. Our main results demonstrate that emptiness of the $Λ$-set implies local controllability and guarantees the existence of minimizing sequences achieving the target in reduced time. We derive strengthened necessary conditions for time-optimal control and provide explicit constructive procedures for approximating generalized controls by ordinary trajectories. These results resolve longstanding questions about relaxation phenomena while extending classical theory to address modern challenges in non-convex optimization, establishing foundations for higher-order analysis in free-time problems.
