Sliding mode control of brushless doubly-fed machine used in wind energy conversion system

This paper presents the applications of the sliding mode control to a brushless doubly fed induction generator (BDFG) used in wind-energy conversion systems. The controller is designed based on the sliding mode control combined with a the stator power winding flux oriented vector principle, the independent control of active and reactive powers has been developed and the performance of proposed the block diagram of the variable speed constant-frequency (VSCF) wind energy generation system is validated in the Matlab/Simulink environment and the computer simulation results obtained confirm the effectiveness of this control strategy.

Sensorless optimal power control of brushless doubly-fed machine in wind power generator based on extended kalman filter

This paper presents a sensorless maximum power point tracking control of brushless double fed machine for variable speed wind energy conversion system based on extended Kalman filter for estimation of rotor speed, The estimated rotational speed is used to regulate the aerodynamic power generated to the point of maximum energy capture, the control strategy for flexible power flow control is developed by applying power winding flux oriented vector control algorithm, the extended Kalman filter is employed to identify the rotor speed which is regarded as a parameter, the analyzed and simulation results in MATLAB/Simulink platform confirmed the good dynamic performance of the proposed sensorless maximal wind energy capture and effectiveness of the estimation of rotational speed at different wind speed.
