本文讨论了两种最常见的控制协同设计协调策略：同时分析和设计以及嵌套控制问题表述。利用文献和来自主动车辆悬架的详细且具有挑战性的 CCD 问题的综合数值结果，提出了对这两种策略的许多实际见解。该研究试图在控制协同设计协调实施之间提供公平的比较和讨论。结果表明，与现有实现相比，计算成本大幅降低，并且方法选择的结论与文献中的常见假设相反。然而，还需要开展更多工作来提供一套强有力的 CCD 实施指南。
This paper tackles perhaps the two most common control co-design coordination strategies: simultaneous analysis and design and the nested control problem formulation. Many practical insights into the two strategies are presented using the literature and comprehensive numerical results from a detailed and challenging CCD problem of an active vehicle suspension. The study conducted attempts to provide a fair comparison and discussion between the control co-design coordination implementations. The results indicate a substantial reduction in computational costs over the existing implementations and conclusions on method selection contrary to common assumptions in the literature. However, additional work is needed to provide a robust set of CCD implementation guidelines.
