摘要

The controller is one of the important parts of the wind turbine system, it is stochastic and nonlinear and the different wind turbine configurations pose a variety of design goals. The majorities of relevant literatures were concerned with the control of horizontal-axis machine. The main achievements and methods of variable structure control, differential geometric control, H∞ robust control, linear optimal control, adaptive control, fuzzy logic control, neural network control, Expert system control and synthesis intelligent control were used in the control of wind energy conversion system stability, speed control system and maximum-power point tracking were surveyed, and some problems to be solved were described simultaneously.
