Nonlinear Dynamic Inversion Control for Wind Turbine Load Mitigation based onWind Speed Measurement

摘要

The design of an advanced controller for wind turbine\udload mitigation is presented. The controller is based on\udNonlinear Dynamic Inversion control methods combined\udwith Pseudo Control Hedging to account for the actuator\udlimits and a two degree of freedom control system\udfor the collective pitch control of the rotor blades. The\udcontroller uses wind speed measurement information to\udadjust to wind gust load. A newly developed wind turbine\udsystem dynamics library in the Modelica language\udis used to model an elastic wind turbine for a simulation\udstudy of the controller. The simulation results show a\udlarge reduction of the gust load on the wind turbine using\udthe proposed controller.
