摘要

本文讨论为非线性球形波浪能转换器（WEC）开发两种非线性控制，以最大限度地利用波浪能量。第一种控制是简单的非线性阻尼控制，它是根据流体动力阻尼系数设计的。然后使用遗传算法对这些控制系数进行优化。第二种是利用庞特里亚金最小原理分析得出的非线性最优控制，以进行比较。研究发现，非线性优化控制能有效利用浮子形状带来的流体力学非线性，从而提高设备的性能。与非线性阻尼控制（NLDC）相比，非线性 bang-singular-bang (BSB) 控制平均提高了 20% 的性能。

Nonlinear control design for a spherical Wave Energy Converter

This paper discusses the development of two nonlinear controls for a nonlinear spherical wave energy converter (WEC) to maximize the energy it harvests from the waves. The first control is a simple nonlinear damping control, which is designed based on the hydrodynamic damping coefficients. These control coefficients are then optimized using a Genetic Algorithm. The second is a nonlinear optimal control derived analytically using the Pontryagin minimum principle for comparison. The study found that the nonlinear optimal control improves the device's performance by effectively leveraging the hydrodynamic nonlinearity from the floater's shape. The nonlinear bang-singular-bang (BSB) control showed an average 20% performance improvement over the nonlinear damping control (NLDC).
