Abstract:
This talk consists of two parts. In the first part, recent results on modeling and control of floating offshore wind turbines are presented. For modeling, a physics-based control-oriented model for the NREL 5MW semi-submersible wind turbine is developed, and its dynamic response is compared with the response of a medium-fidelity NREL FAST model. Various model-based controllers are designed for power regulation and fatigue minimization, and their performances are compared with the baseline PI gain-scheduling controller. In addition, the position control of the floating platform is considered for real-time layout optimization of a wind farm, in order to maximize the total power capture of the wind farm.
In the second part, research on switching LPV control is explained. Switching LPV controller design problems with optimized switching surfaces, smooth switching, and inexact scheduling parameter measurements are presented. It is demonstrated in simulations that the switching LPV control technique has a potential for improving control performance in practical engineering problems.
Brief Bio:
Ryozo Nagamune received Bachelor and Master Degrees from the Department of Control Engineering, Osaka University, Japan, in 1995 and 1997, respectively, and Ph.D. degree in Applied Mathematics from the Division of Optimization and Systems Theory, Royal Institute of Technology, Stockholm, Sweden, in 2002. From 2003 to 2006, he was a Post-Doctoral Researcher at the Mittag-Leffler Institute, University of California at Berkeley, Berkeley, CA, USA, and the Royal Institute of Technology. He has been with the Department of Mechanical Engineering, University of British Columbia, since August 2006, where he is now an Associate Professor. From 2013 to 2014, he was a Visiting Researcher at the National Wind Technology Center, National Renewable Energy Laboratory, Golden, CO, USA, and at Sophia University, Tokyo, Japan. His research interests include robust control theory and its applications to mechatronics systems. He is an Associate Editor of the ASME Journal of Dynamic Systems, Measurement, and Control. He is a Chair of the IEEE Joint Chapter of Control Systems, Robotics, and Automation, and Systems, Man, and Cybernetics Societies in the IEEE Vancouver Section. He presently holds the Canada Research Chair, Tier 2, in Control Engineering.
