Runyu Zhang, Yingying Li, Na Li

摘要:

本文研究了具有时变费用函数和干扰的在线线性二次型调节器(LQR)控制的动态后悔问题。我们考虑的情况下,一个有限的前瞻窗口的费用函数和干扰是在每个阶段。本文研究的在线控制算法属于模型预测控制(MPC)的范畴,并对终端代价进行了特殊的选择,以保证MPC的指数稳定性。证明了这种在线算法的遗憾度随预测长度呈指数快速衰减。本文还研究了预报不准确对扰动的影响。

英文摘要:

In this paper, we study the dynamic regret of online linear quadratic regulator (LQR) control with time-varying cost functions and disturbances. We consider the case where a finite look-ahead window of cost functions and disturbances is available at each stage. The online control algorithm studied in this paper falls into the category of model predictive control (MPC) with a particular choice of terminal costs to ensure the exponential stability of MPC. It is proved that the regret of such an online algorithm decays exponentially fast with the length of predictions. The impact of inaccurate prediction on disturbances is also investigated in this paper.
