L adaptive pitch angle controller of wind energy conversion systems.

In conditions of above rated wind speed, the power output of a wind turbine should be maintained at rated power to prevent overheating of generators and power electronics systems. Furthermore, extreme wind conditions, such as wind gusts, can even lead to shut-downs. In this paper, a novel L adaptive controller is designed for blade pitch control of wind energy conversion systems (WECS) to achieve stable output power and generator speed, in the presence of turbulent wind conditions.
