| Wind power attracts the international governments attention more and more as a new-type of clean energy. The development of wind power technology has been improved continuously and rapidly because of the tireless efforts of a large number of researchers and more and more medium-sized wind farms have been built and put into operation to provide clean energy for us. In recent years, permanent magnet synchronous generator with high efficiency in wind electricity generation has been caused for concern. However, the control of air-gap magnetic field of general permanent magnet synchronous generator is difficult, thus the system control's difficulty is improved. In this paper, a new-type of hybrid excitation permanent magnet synchronous generator (CPPG) of the small wind power systems is researched. This generator can achieve a wide range of flux regulation, real-time control of the generator output voltage, extending the range of wind turbine's power generation and improve the efficiency of wind power generation. It can be maintenance-free and has high reliability benefited from no brushes or slip rings.In this paper, firstly, the research and development situation of wind power generator and its control strategy are summarized, the mathematical model of the new-type of hybrid excitation permanent magnet synchronous generator is established base on the circuit and flux relationship, the principle and the implementations of maximum power point tracking control are analyzed base on the characteristics of CPPG, then built the motor ontology model and simulation model of the entire power system in Matlab/Simulink, and the simulation system for maximum power tracking control is examined and analyzed separately with the strategy of i_d = 0, maximum torque per ampere and minimum loss control, finally, the control software code of DSP chips device is designed and wrote and the current regulator based on the thinking of vector control is designed.
