A Linear Active Disturbance Rejection Control applied for DFIG based Wind Energy Conversion System
نویسندگان
چکیده
This paper proposes the control of a doubly fed induction generator DFIG used in wind turbine energy conversion. The control strategy is based on the linear active disturbance rejection control ADRC to generate the control voltages of the rotor side converter RSC and the grid side converter GSC, due to the changes in control inputs. The ADRC, based on the extended state observer ESO, estimate and compensate in real time all the internal and external disturbance of the physical plant, such as, the parameter uncertainties due to the temperature variation, the cross-coupling terms and the load current variation into the dc link voltage. Simulations results are carried out with MATLAB /SIMULINK.
