摘要:

控制障碍函数(CBFs)为强制动力系统安全性的有效框架,但许多安全约束更自然地以矩阵值条件表达,如正定性或特征值界,标量形式可能引入非光滑性。矩阵控制障碍函数(MCBFs)通过直接强制矩阵值安全约束解决此问题。然而,对于控制输入不出现在一阶导数中的约束,需要高阶形式。尽管标量情况下的扩展已为人所知,但在矩阵情况下仍鲜有研究。本文开发了高阶矩阵控制障碍函数(HOMCBFs),并建立了确保相关约束良定性与可行性的条件,使能够对具有高阶动力学的系统强制执行矩阵值安全约束。进一步地,通过使用最优衰减HOMCBF形式,可确保前向不变性,仅需对最小特征空间施加控制。该框架通过强制双积分系统非线性测量模型的信息矩阵正定性,展示了在定位安全问题中的应用。

英文摘要:

Control barrier functions (CBFs) provide an effective framework for enforcing safety in dynamical systems with scalar constraints. However, many safety constraints are more naturally expressed as matrix-valued conditions, such as positive definiteness or eigenvalue bounds - scalar formulations introduce potential nonsmoothness that complicates analysis. Matrix control barrier functions (MCBFs) address this limitation by directly enforcing matrix-valued safety constraints. Yet for constraints where the control input does not appear in the first derivative, high-order formulations are required. While such extensions are well understood in the scalar case, they remain largely unexplored in the matrix case. This paper develops high-order matrix control barrier functions (HOMCBFs) and establishes conditions ensuring well-posedness and feasibility of the associated constraints, enabling enforcement of matrix-valued safety constraints for systems with high-order dynamics. We further show that, using an optimal-decay HOMCBF formulation, forward invariance can be ensured while requiring control only over the minimum eigenspace. The framework is demonstrated on a double-integrator localization problem by enforcing positive definiteness of the information matrix.
