Korde 9703749 This award supports a 24 month Science and Technology Agency (STA) Postdoctoral Fellowship for Dr. Umesh Korde at the Japan Marine Science and Technology Center (JAMSTEC), Yokosuka, Japan. Dr. Korde will work with Dr. Yukihisa Washio, Senior Research Engineer, on a research project entitled, "Optimal Control of Floating Wave Energy Devices." Over the last two decades, various types of devices have been developed to absorb wave energy, with near-shore, shallow-water devices being far easier to install and maintain. The practical problem currently confronted by researchers, however, is how to develop applications that absorb increased available wave energy in deeper waters. The principal component of most devices is the primary energy converter, a technique that oscillates in response to the waves and converts these oscillations into revolutions via a turbogenerator or reciprocations of a pump. On floating devices, the primary converter motion normally occurs using the floating hull as a reference, a process that reduces the energy-conversion efficiency. Significant improvements would result if one could provide on board the hull an actively controlled body which serves as a steady frame of reference. The primary goal of the proposed research is to develop such a system. The secondary goal is to develop a time-domain control method that adjusts the primary converter dynamics on a wave-by-wave basis to optimize the energy absorbed in irregular waves. ***

Korde 9703749 该奖项支持 Umesh Korde 博士在日本横须贺日本海洋科学技术中心 (JAMSTEC) 获得为期 24 个月的科学技术机构 (STA) 博士后奖学金。 Korde 博士将与高级研究工程师 Yukihisa Washio 博士合作开展一个名为“浮动波浪能装置的优化控制”的研究项目。 在过去的二十年中，已经开发了各种类型的设备来吸收波浪能，近岸浅水设备更容易安装和维护。 然而，研究人员目前面临的实际问题是如何开发能够吸收更深水域中更多可用波浪能的应用。 大多数设备的主要部件是主能量转换器，这是一种响应波浪而振荡的技术，并通过涡轮发电机或泵的往复运动将这些振荡转换为旋转。 在浮动设备上，主转换器运动通常使用浮动船体作为参考来发生，这一过程会降低能量转换效率。 如果能够在船体上提供一个主动控制的主体作为稳定的参考系，将会产生重大的改进。拟议研究的主要目标是开发这样一个系统。 第二个目标是开发一种时域控制方法，该方法可以逐波调整初级转换器动态，以优化不规则波中吸收的能量。 ***
