摘要:

鲁棒模型预测控制算法对于处理预测真实世界系统时因不确定性而产生的不可避免误差至关重要。然而,此类算法的公式化通常会导致保守性与计算复杂度之间的权衡。单调系统便于高效计算可达集,从而能够直接构建一种在开环预测上进行优化的鲁棒模型预测控制方法。我们提出了一种基于可达集划分的方法,以将反馈纳入预测中,从而得到保守性更小的策略。混合单调性的概念使得我们的方法能够扩展到非单调系统。通过一个非线性高维化工串联反应釜案例研究,证明了所提出方法的潜力。

英文摘要:

Robust model predictive control algorithms are essential for addressing unavoidable errors due to the uncertainty in predicting real-world systems. However, the formulation of such algorithms typically results in a trade-off between conservatism and computational complexity. Monotone systems facilitate the efficient computation of reachable sets and thus the straightforward formulation of a robust model predictive control approach optimizing over open-loop predictions. We present an approach based on the division of reachable sets to incorporate feedback in the predictions, resulting in less conservative strategies. The concept of mixed-monotonicity enables an extension of our methodology to non-monotone systems. The potential of the proposed approaches is demonstrated through a nonlinear high-dimensional chemical tank reactor cascade case study.
