Energy and environment have great influence on human survival and social development.Since twenty-first Century,new energy sources,such as wind energy and solar energy,have been widely paid attention to.Wind energy is one of the most energy sources in nature,and it is an ideal green energy source.At present,the main form of wind energy is wind power generation.In order to get high quality power,the control technology of wind turbine is very important.The variable pitch control technology can effectively improve the efficiency of wind power generation,and by controlling the input power of the wind turbine,the output power of the generator can be adjusted and the quality of the power generation can be improved.This paper mainly studies the pitch control technology of wind turbines.The article is composed of the following parts.First,by analyzing the aerodynamics principle of wind turbines,the main factors that affect the performance of wind turbines are obtained.Based on that,the principle of pitch control for wind turbines is expounded,and the main control methods are analyzed,which will lay a foundation for future research.According to the above conclusion,the components of the variable propeller control system are analyzed,and the mathematical model is established on the Matlab/Simulink platform,and the whole model simulation of the variable propeller control system is completed,and the preliminary simulation results are obtained.Then,according to the requirements of the electric paddle control system,a variable rate paddle control method is proposed.A variable rate variable oar controller is designed based on the fuzzy algorithm,and the modeling of variable speed variable propeller control system is completed.The simulation results are obtained,and the reliability of the method is verified.Finally,a variable pitch control system of wind generator based on TMS320F2812 is designed.The control program of the system is compiled with the idea of modularization,and the actual control effect of the control system is verified by the experimental platform.
