摘　　要： 风速、风向及负载的随机性、湍流、尾流效应、塔影效应等的影响,使风力发电系统不但要解决最大风能捕获、电能品质控制两类关键问题,还要解决传动链的疲劳负载、叶片的振颤与翦切、塔身的弯曲与抖振等问题,这些问题实际上都可归结为非线性控制的范畴。该文综述了近年来滑模变结构控制、H∞鲁棒控制在风力发电系统稳定,最大风能捕获及调速系统控制等方面应用研究的主要成果与方法,并提出若干需要解决的问题。 Because the influence of the stochastic of wind speed, wind direction and loads, turbulence, wake effects, tower shadow, not only two key problems of maximumpower transfer and power quality control must be processed, but also the fatigue loads in transmission chain, the vibration and shear of turbine blade, the bent and vibration of tower, have to be solved. These problems can be settled by nonlinear control techniques. This main achievements and methods of variable structure control, H∞ robust control used in the control of wind energy conversion system stability, speed control system and maximumpower transfer are surveyed in this paper, and certain problems to be solved are proposed simultaneously.
