A Comparative Study between FSMC and FSOSMC Strategy for a DFIG-based Wind Turbine System

This paper presents a modelling and sliding mode control (SMC) of a doubly fed induction generator (DFIG) integrated into wind turbine system (WTS) for independent control of reactive and active stator power. For a comparative study, the independent control of reactive and active stator power is ensured in the first step by fuzzy sliding mode controller (FSMC) and the second step by fuzzy second order sliding mode controller (FSOSMC). Finally, the performance of the system is tested and compared by simulation in terms of robustness and reference tracking based on Matlab / Simulink software.
