| Popis: | The Linear Parameter Varying (LPV) control of Wind Energy Conversion Systems (WECS) is a highly motivating subject. The paper deals with the robust control of a Wind Turbine (WT) driven by a Doubly Fed Induction Generator (DFIG). The WT model is enhanced and LPV representation is used for the DFIG, with uncertainties taken in an affine structure, after which, a control strategy is introduced in order to improve the performance of the WT and to assure an optimum energy capture. Also, the purpose is to ensure the stability of the considered system. Therefore, a scenario of a wind speed that varies between 5 m/s and 25 m/s is simulated, where controllers are designed for the generator and turbine and a feedback control strategy is implemented. Also, to prevent saturation, Anti-Windup (AW) structure is considered for the pitch control. The results and details for the regulators are discussed in the last section of this paper. |
