Design of Control System for Wind Turbine Electric Pitch

The operating principle of an electric pitch system of wind turbine is introduced in this paper, and three-phase PMSM (permanent magnetism synchronous motor) is chosen as the executive motor of the proposed system. TMS320F2812 is designed as the core of the electric propeller servo control system hardware based on the analysis of the servo variable pitch control system´s principle, and a system software programming is carried out. Simulation and experiment studies are performed using MATLAB. Simulation studies indicated that the new system generate superior results over conventional system such as the dynamic response of the servo system speed is fast, and efficiency can be effective in the proposed system.
