A wind energy conversion system (WECS) model is presented, including wind turbine and brushless doubly fed machine working as a generator. The WECS is decoupled into two subsystems by synchronous frame transformation. Furthermore, a double-loop controller is applied to make the system follow the characteristics of the reference model. It's well known that a particular wind speed corresponds to an maximum power output. By considering the complex structure of the BDFM (brushless doubly-fed machine), a disturbance rejection controller (ADRC) is used in the inner loop of the control system in order to achieve power-decoupling control. Besides, linear model following control (LMFC) is used in the outer loop to make the generator effectively track the characteristics of the model. Simulation results indicate that doubleloop controller enables the output power of the system to track the given power and achieves perfect model following, which verifies the validity of the control algorithm.
