%X <span style=\"font-size:14px;\">过去，波浪能发电装置依照能量转换方式的不同可以分为三类：振荡水柱式、振荡体式、越浪式。目前，各国现有的波浪能海洋浮标普遍存在体积小、结构简单、供电低的缺点，导致生存能力和承载能力较差，大大限制了浮标的可靠性和应用范围。与大型波浪能装置或其他海上设施相比，振荡体类型体积小，耗电量少。海洋中有足够的波浪能来提取它。波浪动力浮标几乎可以部署在所有海域。因此，开发振荡体式波能发电装置是解决海洋浮标供电问题的有效途径。本文研究一种搭载PTO能量输出系统的振荡浮子式波浪能装置，在不同激励条件下的动能响应以及能量转换，并建立出一种普适性系统模型，并通过局部遍历寻优算法，得到系统最大功率时的阻尼C = 10,000。</span><br />
<span style=\"font-size:14px;\">In the past, wave energy power generation devices can be divided into three types according to dif-ferent energy conversion modes: oscillating water column type, oscillating body type and overtop-ping type. At present, the existing wave energy buoys in various countries generally have the disadvantages of small size, simple structure and low power supply, resulting in poor viability and bearing capacity, which greatly limits the reliability and application range of buoys. Compared with large wave energy installations or other offshore facilities, the oscillating body type has small volume and low power consumption. There is enough wave energy in the ocean to extract it. Wave-dynamic buoys can be deployed in almost all sea areas. Therefore, the development of oscillatory wave energy power generation device is an effective way to solve the power supply problem of marine buoys. This paper studies the kinetic energy response and energy conversion of an oscillating float-type wave energy device with PTO energy output system under different excitation conditions, and establishes a universal system model, and obtains the damping C = 10,000 at the maximum power of the system through local ergodic optimization algorithm.</span>
