Control of wind turbines using memory-based method

Control can improve the dynamic performance of wind turbines. This work investigates the memory-based method for variable speed control of wind turbines. The main idea behind this approach is to use certain gathered information such as past and recent rotor speed as well as previous control experience to generate new control action. Both theoretical and simulation studies show that this method, when applied to pitch control of wind turbines, is able to ensure stable tracking of rotor speed under varying operation conditions.
