It is challenging to design a controller for a wind turbine system because of its nonlinear time-varying dynamics. To resolve this issue, linear parameter-varying (LPV) control theory has been applied in the past 10years to deal with nonlinear and wind-speed-dependent dynamics. Before applying the LPV control method, it is required to transform the nonlinear model of the system to an LPV model. The main objectives of this research are to model a 5-megawatt (MW) Reference Wind Turbine for Offshore System as an LPV system, develop a nonlinear wind turbine simulator using MATLAB/Simulink to validate the LPV model, and conduct a preliminary study on LPV control design to test the simulator, which will be used in the future research for applying different LPV control techniques, such as switching LPV control, LPV anti-windup control, and others.
