本文研究在嵌入\\(\mathbb{R}^3\\)的光滑流形上运动的运动学独轮机器人的路径跟踪控制问题。目标是在不施加时间参数化的情况下稳定流形上的一维路径,从而将问题与轨迹跟踪区分开来。在几何框架下,我们提出了两种反馈律:一种用于规定非零平移速度的静态控制器,以及一种基于平移速度动态扩展的动态控制器。通过将路径提升到曲面的单位切丛,我们刻画了相应的路径跟踪流形并建立了其控制不变性。然后我们证明,在适当的正则性条件下,所提出的控制器使路径跟踪流形局部指数稳定。数值仿真验证了所提出的控制器。代码和动画可在该https URL公开获取。
英文摘要
This paper studies path-following control for a kinematic unicycle evolving on a smooth manifold embedded in \(\mathbb{R}^3\). The objective is to stabilize a one-dimensional path on the manifold without imposing a temporal parameterization, thereby distinguishing the problem from trajectory tracking. Working in a geometric framework, we propose two feedback laws: a static controller for prescribed nonzero translational speed and a dynamic controller based on a dynamic extension of the translational speed. By lifting the path to the unit tangent bundle of the surface, we characterize the corresponding path-following manifold and establish its control invariance. We then show that the proposed controllers render the path-following manifold locally exponentially stable under suitable regularity conditions. A numerical simulation illustrates the proposed controller. Code and animations are publicly available at https://gradslab.github.io/UnicycleOnManifolds/.
