具有状态和输入约束的线性系控制的在线凸优化算法

An online convex optimization algorithm for controlling linear systems with state and input constraints

Marko Nonhoff, Matthias A. Müller

摘要:

本文研究线性动力系统在时间上受逐点约束的控制问题。我们提出了一个类似于在线梯度下降的算法,可以处理时变和先验未知的凸费用函数,同时限制系统的状态和输入多面体约束集。通过对算法性能的分析,发现如果费用函数的变化在时间上是次线性的,则可以实现次线性的后悔。最后,我们提出了一个简单的例子来说明实现细节以及算法的性能,并表明该算法确保约束满足。

英文摘要:

This paper studies the problem of controlling linear dynamical systems subject to point-wise-in-time constraints. We present an algorithm similar to online gradient descent, that can handle time-varying and a priori unknown convex cost functions while restraining the system states and inputs to polytopic constraint sets. Analysis of the algorithm's performance, measured by dynamic regret, reveals that sublinear regret is achieved if the variation of the cost functions is sublinear in time. Finally, we present a simple example to illustrate implementation details as well as the algorithm's performance and show that the proposed algorithm ensures constraint satisfaction.
