Abstract :
Currently the doubly fed induction machine (DFIM) is often used in wind power plants. The digital rotor current controller is always based on DFIM models linearized within a sampling period which does not correspond to the nonlinear nature of the DFIM. The paper deals with a nonlinear control scheme with direct decoupling and presents some first investigation results. This new controller helps to improve ride-through of the wind turbine during grid faults
