The Active Pitch Control Research of Wind Turbine Based on Feedback Linearization Method

The necessity and advantage of active angle control were expounded based on the analysis of the active angle control at wind velocity higher in wind electric power system and the weak open-loop performance of turbine model.The theory of state feedback linearization was adopted to create its accurate linearized model controlled with the optimal control method.The model was simulated under MATLAB,and the wave shapes were analysed with comparison.
