• Bond graph modeling and simulation of wind turbine systems 

      Bakka, Tore; Karimi, Hamid Reza (Journal article; Peer reviewed, 2013)
      This paper addresses the problem of bond graph methodology as a graphical approach for the modeling of wind turbine generating systems. The purpose of this paper is to show some of the benefits the bond graph approach has, ...
    • Multiobjective Optimization and Multivariable Control of Offshore Wind Turbine System 

      Bakka, Tore (Doctoral dissertations at University of Agder; no. 68, Doctoral thesis, 2013)
      Renewable energy is a hot topic all over the world. Nowadays, there are several sustainable renewable power solutions out there; hydro, wind, solar, wave and biomass to name a few. Most countries have a tendency to want ...
    • Robust H∞ dynamic output feedback control synthesis with pole placement constraints for offshore wind turbine systems 

      Bakka, Tore; Karimi, Hamid Reza (Journal article; Peer reviewed, 2012)
      The problem of robust ∞ dynamic output feedback control design with pole placement constraints is studied for a linear parameter-varying model of a floating wind turbine. A nonlinear model is obtained and linearized using ...
    • Theoretical and experimental study of friction emulation and compensation 

      Bakka, Tore; Bächer, Johannes (Master thesis, 2010)
      This project deals with hydraulics, mechanics, electronics, dynamic modeling and control theory. The focus is on constructing a test rigg in order to to emulate desired friction and compensate for this with a control loop. ...
    • Wind turbine modeling using the bond graph 

      Bakka, Tore; Karimi, Hamid Reza (Chapter; Peer reviewed, 2011)
      This paper addresses the problem of bond graph methodology as a graphical approach for modeling wind turbine systems. In this case, we consider the modeling of a wind turbine system with individual pitch control scheme and ...
