This paper introduces the wind energy conversion system optimal tip speed ratio control algorithm is designed, main purpose is to achieve maximum power point tracking of wind power system . The beginning of the paper introduces the general situation of wind power at home and abroad, laid the writing background for this article. Then the article expounds the basic principle of wind power generation system, emphatically introduces the structure and composition and Bates theory of wind turbine, which is the basis of this article. Then, this paper analyzes the basic principle of the maximum power point tracking control algorithm, and the characteristics of the optimal tip speed ratio control, ready for the design of control system. Then aiming at optimal tip speed ratio control characteristics of fixed step length algorithm, designed the corresponding control algorithm and PI controller, by choosing the right PI parameters, obtained the ideal track effect, so as to realize the goal of control required. The last is the focus of this article, the simulation of Matlab environment. First, I established the simulation model of wind power system, and then realized in Matlab environment the optimal tip speed ratio control algorithm and the control algorithm simulation results are analyzed. In a word, through the design and simulation of wind power generation system, impl
