虽然一些工程领域已受益于系统设计优化研究，但波浪能转换器尚未成功地将此类分析纳入实际工程工作流程中。当前波浪能转换器设计的迭代方法导致了次优解决方案。这篇简短的论文介绍了一个开源 MATLAB 工具箱，用于对波浪能转换器进行设计优化研究，其中可以轻松包含取力器行为和实际约束。该工具采用了自适应控制协同设计方法，其中约束最优控制器用于模拟设备动态并填充用户选择的任意目标函数。简要解释了该工具的结构和基础理论。为了展示该工具的功能、验证其功能并开始探索一些基本的波浪能转换器设计关系，提出了三个概念性案例研究。特别是，显示了在设计优化中考虑（和约束）设备运动和力的大小的重要性。
While some engineering fields have benefited from systematic design optimization studies, wave energy converters have yet to successfully incorporate such analyses into practical engineering workflows. The current iterative approach to wave energy converter design leads to sub-optimal solutions. This short paper presents an open-source MATLAB toolbox for performing design optimization studies on wave energy converters where power take-off behavior and realistic constraints can be easily included. This tool incorporates an adaptable control co-design approach, in that a constrained optimal controller is used to simulate device dynamics and populate an arbitrary objective function of the user’s choosing. A brief explanation of the tool’s structure and underlying theory is presented. To demonstrate the capabilities of the tool, verify its functionality, and begin to explore some basic wave energy converter design relationships, three conceptual case studies are presented. In particular, the importance of considering (and constraining) the magnitudes of device motion and forces in design optimization is shown.
