AI总结:

本文研究最大疏离控制中的价值函数,证明在可控系统模型假设下,初始状态可达集内价值函数连续且严格凸,对分析优化敏感性和模型预测控制稳定性具有重要意义。

摘要:

在本文中,我们研究最大疏离控制中的价值函数。最大疏离控制,也称为稀疏控制,是在可行控制中L0最优控制。尽管L0度量是不连续且非凸的,我们证明价值函数,或控制的最小L0范数,是在可达集内初始状态的连续且严格凸函数,基于对受控系统模型的假设。这一性质很重要,特别是在讨论初始状态不确定性对最优性的敏感性以及利用价值函数作为模型预测控制中的Lyapunov函数来研究稳定性时。

英文摘要:

In this brief paper, we study the value function in maximum hands-off control. Maximum hands-off control, also known as sparse control, is the L0-optimal control among the admissible controls. Although the L0 measure is discontinuous and non- convex, we prove that the value function, or the minimum L0 norm of the control, is a continuous and strictly convex function of the initial state in the reachable set, under an assumption on the controlled plant model. This property is important, in particular, for discussing the sensitivity of the optimality against uncertainties in the initial state, and also for investigating the stability by using the value function as a Lyapunov function in model predictive control.
