摘要:

本文针对具有复杂时变输入约束的非线性系统,提出了一种基于控制障碍函数(Control Barrier Function,CBF)的新型控制器。为处理这些约束,我们引入辅助控制输入,将原系统转化为增广系统,从而将输入约束问题重构为输出约束问题。该变换简化了二次规划(Quadratic Programming,QP)公式,增强了与CBF框架的兼容性。因此,所提方法能够系统性地处理复杂的、时变的且与状态相关的输入约束。我们通过数值算例验证了该方法的有效性。

英文摘要:

In this paper, we propose a novel Control Barrier Function (CBF) based controller for nonlinear systems with complex, time-varying input constraints. To deal with these constraints, we introduce an auxiliary control input to transform the original system into an augmented one, thus reformulating the constrained-input problem into a constrained-output one. This transformation simplifies the Quadratic Programming (QP) formulation and enhances compatibility with the CBF framework. As a result, the proposed method can systematically address the complex, time-varying, and state-dependent input constraints. The efficacy of the proposed approach is validated using numerical examples.
