Pitch regulated LQG controller design for variable speed wind turbine

This paper deals with the design of LQG controllers for pitch regulated, variable speed wind turbines where the controller is used primarily for controlling the pitch angle through a collective pitch angle in the high wind speed in order to guarantee the power regulation. The performance of the control is compared to that of a PID controller using the SUT-1MW wind turbine and wind model. The results show that LQG controller have good performance than PID controller.
