GOALI: Dynamic Multi-Mode Design Methodology for Efficient Energy Conversion System Design

本次GOALI奖的研究目标是开发一种高效能量转换系统的动态多模式设计方法。该研究将描述和模拟工程系统的关键设计方面，该系统必须经历多种操作条件，形式化设计方法，并与工业合作伙伴卡特彼勒公司一起在现实的能量转换系统设计案例（柴油发动机）中验证该方法。设计方法将在多学科设计优化框架中利用平衡（或互补）约束的思想。本研究的结果将为工业中包括替代能源在内的能源转换系统设计实践中出现的动态多模式系统设计提供并验证一类新的问题和解决方案。如果成功，这项研究的结果将克服现有设计方法在可扩展性、动态行为和自主选择操作模式方面的局限性。长期的环境和社会效益包括减少排放，减少对环境的负面影响，以及开发更清洁的能源，如太阳能，风能，清洁煤，氢气等。设计能源转换系统，包括柴油发动机，将更有效地遵守更严格的环境监管政策。通过采用新的多模式设计方法，制造商将能够实现符合成本效益的目标，同时生产性能更好的能量转换系统。女性和少数族裔学生将受益于与女性工程项目和莫里尔工程项目合作的教育努力，研究生将通过产学研助学金项目获得宝贵的研究经验。

The research objective of this GOALI award is the development of a dynamic multi-mode design methodology for an efficient energy conversion system. The research will characterize and model key design aspects of an engineering system that must undergo multiple operating conditions, formalize the design methodology, and validate the methodology in a realistic energy conversion system design case (diesel engine) with an industrial partner -- Caterpillar, Inc. The design methodology will utilize the idea of equilibrium (or complementarity) constraints in a multidisciplinary design optimization framework. The results of this research will provide and validate a new class of problems and solutions for dynamic multi-mode system design that is emerging from the energy conversion system design practices in industry, including alternative energy sources. If successful, the results of this research will overcome limitations in existing design methods with respect to scalability, dynamic behavior and autonomous selection of operational modes. Long-term environmental and societal benefits include reducing emissions, decreasing negative environmental impact, and developing cleaner energy sources such as solar, wind, clean coal, hydrogen, among others. Designing energy conversion systems, including diesel engines, will be more efficient in complying with the stricter environmental regulatory policies. By adopting the new multi-mode design methodology, manufacturers will be able to achieve the goal of cost-effective compliance while producing energy conversion systems with better performance. Women and minority students will benefit from the education efforts in partnership with the Women in Engineering Program and the Morrill Engineering Program, and graduate students will gain valuable research experience via the industry-university research assistantship program.
