Abstract

When the wind speed is above the rated value, the traditional control strategy is variable pitch control, and the control method is PI control. However, variable pitch wind turbines have strong nonlinear characteristics due to the natural wind which random changes with time and space. For the pitch angle control agencies in the large wind turbines, the bp neural network controller is designed and the controller of the FPGA-based hardware problem is discussed. The analysis of the neural network controller features reconstructed is presented by its three major reconfiguration units. The controller can be established based on the SG/Simulink. The simulation results show that the FPGA-based neural network controller can keep the constant output of wind turbine power, the working efficiency of the variable pitch servo system is improved , and a better idea is provided for the hardware implementation of the neural network in the wind energy conversion system.
