Clean renewable energy extraction solutions are becoming a crucial practice in today’s society. Many different sources are utilized including ocean energy, and in particular, ocean waves. In deep water conditions, ocean waves can become very power dense, continuous, and forecastable. The variability in wave height, velocity, and frequency make it challenging to capture wave power economically. The wave front parallel wave energy converter (WEC) is a promising device that is currently under research. Its method of power capture is a buoyant vessel oriented normal to oncoming waves with a mechanical structure coupled to an electric generator. This work explores the implementation of known control methods on a novel wave front parallel WEC developed by Rohrer Technologies, Inc. This device is known as the RTI F2 and uses a buoyant vessel configuration. Its orientation allows for power to be absorbed from oncoming waves in the forms of heave (up-and-down) and surge (front-to- back) motions. Experimental data is obtained across various wave conditions, plate angles, vessel weights, and control strategies at the University of New Hampshire’s Chase Laboratory. This data is presented along with corresponding conclusions.
