虽然集成的物理和控制系统协同设计已经在几个工程系统设计应用中成功地得到了证明，但它主要是以确定性的方式应用的，而不考虑不确定性。一个机会存在，研究非确定性的协同设计策略，考虑到各种不确定性的综合协同设计框架。基于可靠性的设计优化（RBDO）是这样一种方法，可以用来确保优化的系统设计得到满足所有的可靠性约束，考虑特定的系统不确定性。虽然在协同设计和RBDO分别取得了显着的进步，鲜为人知的方法，基于可靠性的动态系统设计和控制设计优化被认为是共同的。在这篇文章中，基于可靠性的协同设计的配方和算法进行了比较研究，协同设计问题与RBDO框架相结合，产生的解决方案，包括最优系统设计和相应的控制轨迹，满足所有的可靠性约束的参数不确定性的存在。所提出的研究旨在奠定基础的可靠性为基础的协同设计问题提供了一个比较潜在的设计配方和解决问题的策略。具体的问题配方和概率分析算法进行了比较，使用两个数值例子。此外，通过水平轴风力涡轮机的结构和控制设计问题，证明了基于可靠性的协同设计方法的实际效果。
While integrated physical and control system co-design has been demonstrated successfully on several engineering system design applications, it has been primarily applied in a deterministic manner without considering uncertainties. An opportunity exists to study non-deterministic co-design strategies, taking into account various uncertainties in an integrated co-design framework. Reliability-based design optimization (RBDO) is one such method that can be used to ensure an optimized system design being obtained that satisfies all reliability constraints considering particular system uncertainties. While significant advancements have been made in co-design and RBDO separately, little is known about methods where reliability-based dynamic system design and control design optimization are considered jointly. In this article, a comparative study of the formulations and algorithms for reliability-based co-design is conducted, where the co-design problem is integrated with the RBDO framework to yield solutions consisting of an optimal system design and the corresponding control trajectory that satisfy all reliability constraints in the presence of parameter uncertainties. The presented study aims to lay the groundwork for the reliability-based co-design problem by providing a comparison of potential design formulations and problem–solving strategies. Specific problem formulations and probability analysis algorithms are compared using two numerical examples. In addition, the practical efficacy of the reliability-based co-design methodology is demonstrated via a horizontal-axis wind turbine structure and control design problem.
