AI总结:

本文提出了一种基于高阶控制屏障函数的反馈优化方法,确保系统始终满足状态约束并实现稳定最优解。

摘要:

反馈优化是指一类将控制系统引导至解决优化问题的稳态的方法。尽管在该领域取得了巨大进展,仍有一个重要问题尚未解决:始终强制状态约束。解决这一难题的困难在于在安全执行和闭环稳定性之间进行权衡,并确保闭环平衡点与优化问题的极值点之间的等价性。在本工作中,我们提出了一种反馈优化方法,通过高阶控制屏障函数在所有时刻强制状态约束。我们提供了关于所提出控制器动力学的几个结果,包括well-posedness(良定义性)、安全保证、平衡点与极值点之间的等价性,以及局部和全局(在某些凸情况下)最优解的渐近稳定性。各种仿真示例展示了我们的结果。

英文摘要:

Feedback optimization refers to a class of methods that steer a control system to a steady state that solves an optimization problem. Despite tremendous progress on the topic, an important problem remains open: enforcing state constraints at all times. The difficulty in addressing it lies on mediating between the safety enforcement and the closed-loop stability, and ensuring the equivalence between closed-loop equilibria and the optimization problem's critical points. In this work, we present a feedback-optimization method that enforces state constraints at all times employing high-order control-barrier functions. We provide several results on the proposed controller dynamics, including well-posedness, safety guarantees, equivalence between equilibria and critical points, and local and global (in certain convex cases) asymptotic stability of optima. Various simulations illustrate our results.
