英文摘要： In this project, a new generating system by low-speed wind power is proposed. The basic structure, operating mechanism, as well as the control method, will be analyized in depth. The hybrid magnetic suspension system with low-power consumption is proposed to reduce frictional resistance and increase the flexibility of system's stiffness to restrain autooscillation. The direct drive structure of the switched reluctance generator is excepted to reduce transmission losses and increase the maximum power point tracking speed. An novel automatic navigation wind energy collect device is adopted to improve the utilization of wind power. This research mainly forcuses on the system models, dynamic decoupling and compound intelligent control under complex working conditions. To meet the demands of wide-speed-range generating and more smoothly running torque, a power control method of switched reluctance generator based on multi-model switching is proposed, the smoother torque predicting strategies and the forms of carrying out distributed type adaptive intelligent sliding-mode control are researched. The excitation mechanism, nature characterization and active restrain method of the vertical axis wind turbine main spindle vibration are analyzied. Aimed to coordinate the stability and tracking accuracy of the machine, the i
