Most wind turbines installed have traditional architectures: double-fed asynchronous machine or direct drive with full conversion, both containing several levels of control composed of PI controllers. In our application, a robust 3rd-generation-CRONE controller is used to manage a planetary gearing ratio upstream of a synchronous generator directly connected to the grid. Thus, the speed of the low shaft is controlled and unlike other architectures, no system of power electronics is required for conversion. This CRONE approach is a robust control methodology based on fractional order differentiation.
