The United Nations has designated the 2020s as the “Decade of Ocean Science for Sustainable Development”. Along the long coastlines of the US, Ireland, and the UK, ocean waves represent a vast, untapped, high-density power source. It has been estimated that wave energy has the potential to supply at least one third of US electricity demand. In spite of the huge potential of wave energy to provide power, wave energy conversion is still in its infancy worldwide with none of the wave energy converters (WEC) to date achieving widespread acceptance. This Leading Engineering for America's Prosperity, Health, and Infrastructure (LEAP-HI) project will research the fundamental theory and design tools needed to design practical wave energy converter systems in an integrated fashion. It will be completed through interdisciplinary collaboration of five investigators across three countries throughout the co-design process, from early concept design and components innovation to system integration and field validation. The success of the research on wave energy conversion will help mitigate the global energy crisis, combat climate change, relieve environmental concerns, accelerate blue economy development, and benefit society. It will also serve as a demonstration to inspire worldwide collaborations to solve the global crisis of energy sustainability and establish US-European collaborative leadership in the emerging field of the blue economy. For WECs to efficiently convert energy from wave to wire, multidisciplinary research is required, including a wave capture structure (WCS) to capture the oscillating irregular wave energy as mechanical energy, a power take-off (PTO) subsystem to convert mechanical energy into electricity, and advanced control to adapt the device to irregular wave excitations and optimize power capture. Each of these modules takes domain-specific expertise, which is conventionally addressed sequentially by domain experts. Such a sequential design paradigm neglects the strong couplings among WCS hydrodynamics, PTO dynamics, and system control, which generally results in a sub-optimal or even infeasible design. This transdisciplinary research project aims to establish an integrated design paradigm by testing and validating a radically new control co-design approach to create mutually-efficient PTO and WCS, with active mechanical motion rectification (AMMR), nested co-optimization, and advanced control. The program is a disruptive paradigm switch from the common sequential “design and then control” approach to a concurrent “design for control” and “control for design” approach to holistically design and optimize the entire WEC device’s geometry, system layout, PTO, and control system for significantly improved performance. This research will create fundamental knowledge and tools for coupled modelling, design and control of the WEC system to drive the convergence of wave energy conversion technologies. The research will impact the quality and diversity of education at four universities through multidimensional technical and professional skill trainings, international internships, opportunities for underrepresented minorities and women, and unique hands-on experiences for K-12 and community college students.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

联合国将 2020 年代定为“海洋科学促进可持续发展十年”，在美国、爱尔兰和英国的漫长海岸线上，海浪代表着巨大的、未开发的高密度能源。据估计，波浪能有潜力满足美国至少三分之一的电力需求尽管波浪能提供电力的潜力巨大，但波浪能转换在全球范围内仍处于起步阶段，还没有波浪能转换器（WEC）。迄今为止这项美国繁荣、健康和基础设施领先工程 (LEAP-HI) 项目将研究以综合方式设计实用波浪能转换器系统所需的基础理论和设计工具，该项目将通过跨学科合作完成。来自三个国家的五位研究人员参与了整个协同设计过程，从早期概念设计和组件创新到系统集成和现场验证，波浪能转换研究的成功将有助于缓解全球能源危机、应对气候变化、缓解环境问题。 、加快蓝色经济发展，效益它还将作为一个示范，激励全球合作解决全球能源可持续性危机，并在新兴的蓝色经济领域建立美国与欧洲的合作领导地位，以有效地将能源从海浪转化为有线、多学科研究。需要包括用于捕获振荡的不规则波浪能作为机械能的波浪捕获结构（WCS）、用于将机械能转换为电能的动力输出（PTO）子系统以及使设备适应不规则波浪激励的高级控制和优化功率这些模块中的每一个都需要特定领域的专业知识，而这些专业知识通常由领域专家按顺序解决。这种顺序设计范式忽略了 WCS 流体动力学、PTO 动力学和系统控制之间的强耦合，这通常会导致次优或不理想的结果。这个跨学科研究项目旨在通过测试和验证全新的控制协同设计方法来建立集成设计范例，以创建相互高效的 PTO 和 WCS，并具有主动机械运动校正 (AMMR)、嵌套功能。该计划是一种颠覆性的范式转换，从常见的顺序“设计然后控制”方法到并行的“控制设计”和“设计控制”方法，以整体设计和优化整个 WEC 设备。这项研究将为 WEC 系统的耦合建模、设计和控制创建基础知识和工具，以推动波浪能转换技术的融合。四所大学的教育多样性通过多维技术和专业技能培训、国际实习反映了代表性不足的少数族裔和女性的机会，以及 K-12 和社区学院学生的独特实践经验。该奖项符合 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准。
