变形波能转换器的研究近年来受到越来越多的关注。本文从拉格朗日力学的角度出发，建立了轴对称变形浮标波浪能转换器的动力学模型。采用假设模态法对浮标的柔性模态进行近似。采用被动控制，实现砰砰控制算法。数值模拟研究表明，所建立的模型在研究柔性壳浮标的行为和球形变形浮标波浪能转换器的整体性能方面具有实用价值。
The study of variable-shape wave energy converters has been receiving more attention recently. In this work, a dynamic model for axisymmetric Variable-Shape Buoy Wave Energy Converters is derived within the context of Lagrangian mechanics. The assumed modes method is used to approximate the flexible modes of the buoy. Passive control is adopted that implements a bang-bang control algorithm. A numerical simulation case study is presented that demonstrates the utility of the developed model in studying the behavior of the flexible shell buoy and the overall performance of the spherical Variable-Shape buoy Wave Energy Converter.
