Model Predictive Control of a Nonlinear 2-Body Point Absorber Wave Energy Converter With Estimated State Feedback

Creator:: Amann, Kai Uwe, Magaña, Mario E., and Sawodny, Oliver
Abstract:: Ocean wave energy has the potential to significantly contribute to sustainable power generation in coastal regions. Much of the research effort has gone into developing time domain state space models of point absorber wave energy converters (WECs) and subsequently into model-based optimal control to efficiently harvest the maximum possible amount...

Decentralized Model Predictive Control for Wave Energy Converter Arrays

Creator:: Oetinger, Daniela, Magaña, Mario E., and Sawodny, Oliver
Abstract:: Most of the research on wave energy conversion has been focused on the characterization of the dynamic behavior of arrays of uncontrolled WECs in specific configurations, in order to quantify changes in the wave fields and absorbed power without active control. To maximize wave energy conversion, however, it is necessary...

Model Predictive Control for Underwater Robots in Ocean Waves

Creator:: Fernández, Daniel C.
Abstract:: Underwater robots beneath ocean waves can benefit from feedforward control to reduce position error. This thesis proposes a method using Model Predictive Control (MPC) to predict and counteract future disturbances from an ocean wave field. The MPC state estimator employs a Linear Wave Theory (LWT) solver to approximate the component...
