基于二次规划的控制障碍函数诱导的非期望平衡

On the Undesired Equilibria Induced by Control Barrier Function Based Quadratic Programs

Xiao Tan, Dimos V. Dimarogonas

摘要:

本文分析了一般非线性仿射控制系统在采用控制障碍函数诱导的二次规划控制器进行反馈时的系统行为。特别是,我们描述了闭环系统的可能的平衡点的存在性和位置,并提供了分析结果,设计参数如何影响他们。在此基础上,对现有的基于二次规划的控制器进行了简单的改进,该控制器在不做任何其他假设的情况下,继承了安全集前向不变性的性质,并进一步保证了安全集内部不需要的平衡点和一类边界平衡点的完全消除,以及原点的局部渐近稳定性.数值例子给出了理论讨论的同时。

英文摘要:

In this paper, we analyze the system behavior for general nonlinear control-affine systems when a control barrier function-induced quadratic program-based controller is employed for feedback. In particular, we characterize the existence and locations of possible equilibrium points of the closed-loop system and also provide analytical results on how design parameters affect them. Based on this analysis, a simple modification on the existing quadratic program-based controller is provided, which, without any assumptions other than those taken in the original program, inherits the safety set forward invariance property, and further guarantees the complete elimination of undesired equilibrium points in the interior of the safety set as well as one type of boundary equilibrium points, and local asymptotic stability of the origin. Numerical examples are given alongside the theoretical discussions.
