具有可调不确定集的鲁棒模型预测控制

Robust Model Predictive Control with Adjustable Uncertainty Sets

Yeojun Kim, Xiaojing Zhang, Jacopo Guanetti, Francesco Borrelli

摘要:

在本文中,我们提出了鲁棒模型预测控制(MPC)问题的可调不确定性集。与已知不确定性集的标准鲁棒MPC问题相比,我们将问题中的不确定性集视为额外的决策变量。特别是,给定一个用于调整不确定性集的度量,我们解决了确定这些不确定性集的最佳大小和形状的问题,同时确保鲁棒的约束满足。本文的重点是确保约束满足无限的地平线,也被称为持久的可行性。我们表明,类似于在标准的鲁棒MPC,持久的可行性,可以保证,如果终端集是一个不变的系统的状态和可调的不确定性集。我们还提出了一个算法来计算这样的不变集,并说明我们的方法在合作自适应巡航控制应用程序的有效性。

英文摘要:

In this paper, we present Robust Model Predictive Control (MPC) problems with adjustable uncertainty sets. In contrast to standard Robust MPC problems with known uncertainty sets, we treat the uncertainty sets in our problems as additional decision variables. In particular, given a metric for adjusting the uncertainty sets, we address the question of determining the optimal size and shape of those uncertainty sets, while ensuring robust constraint satisfaction. The focus of this paper is on ensuring constraint satisfaction over an infinite horizon, also known as persistent feasibility. We show that, similar as in standard Robust MPC, persistent feasibility can be guaranteed if the terminal set is an invariant set with respect to both the state of the system and the adjustable uncertainty set. We also present an algorithm for computing such invariant sets, and illustrate the effectiveness of our approach in a cooperative adaptive cruise control application.
