Outline of Final Research Achievements	The wind power generation system which is most influential in renewable energy has been widely introduced all over the world in recent years, and its introduction is expected in the future. However, due to the occurrence of shaft torsional of the wind power generation system, system failure may occur. In this research, we propose a method to suppress the shaft torsional phenomenon occurring in wind power generation system by H infinity controller. We also propose an operation method that can continue operation at high wind speed.
