摘要
Abstract
The sensorless operation and its control method are studied in order to enhance the reliability of VSCF DFIG systems for wind turbines. And the basic structure and control theory of PI Adaptive System were introduced. The control methods which use the error of electromagnetic torque and stator flux as the input of PI controller are introduced. The simulations by Matlab/Simulation are implemented to study and compare these two control methods. The simulation results show that they can help the observation speed track the actual speed accurately and meet the requirement of vector control of double-fed motor.关键词
