摘要

Different wind turbines controllers have been so far introduced. Each controller has own advantages and disadvantages depending on the control goal and turbine model. This paper presents three major models for wind turbines including linear and non-linear dynamic model and General Electric rotor two-mass system. Then, six important control methods consisting of pitch control, lime varying variable slate estimator, hybrid adaptive control with PID, non-linear control model using FAST method, Yaw vector control, slip-mode control method for variable-speed wind turbine are reviewed. The above-mentioned control methods are themselves divided into sub-controllers based on their operating conditions. Therefore, current models and controllers of wind turbines are reviewed, and characteristics of each controller are discussed. It is realized that in many cases the turbine rotor speed oscillations have not been taken into account. These oscillations have harmful impacts on the turbine, such as frequency fluctuations of induction generator induced voltage and high stress on the shaft of turbine and generator.
