An optimal desgsin for variable speed wind turbines based on LQG

الملخص EN

In this paper, propose an optimal control design for variable speed wind turbine subject to disturbance wind and white noise.

The dynamic modeling of the wind turbine and its linearization are derived, and its performance has been established using MATLAB environment.

This method includes a description and some discussion of the Kalman state estimator, and application, particularly in the area of wind turbine system, to control the angular speed based on LQG (Linear Quadratic Gaussian).

The simulation results show, the proposed LQG controller of the system gives good response and have excellent performance when compare with LQR (Linear Quadratic Regulator) controller.
