摘　　要： 针对风力发电机组非线性、时变性的问题,采用模糊自适应PID控制器作为变桨控制器,使变桨控制既具备模糊控制较强的适应能力,又拥有PID控制较高的精度。通过模型代码生成技术将模糊自适应PID控制器下载到风电机组控制系统的控制器中,在风场选取风机进行对比试验,结果表明,变桨控制采用模糊PID控制方式的机组功率输出更加平稳,同时控制响应更加及时,且在变桨控制中调控平稳,对传动系统及变桨执行机构损耗小。 Aiming at the problems of nonlinear,time-varying in the wind turbines,fuzzy adaptive PID controller was established as a variable pitch controller.The controller of fuzzy adaptive PID control system has not only a strong adaptability of fuzzy control,but also a higher accuracy of the PID control.The fuzzy adaptive PID controller was downloaded to the controller of the wind turbine control system through the model code generation technology.The wind turbine was selected for the comparison experiment.The results show that fuzzy adaptive PID control system has a more smoothly output and more timely control response.And at the same time,the regulation of this controller is smooth in the pitch control process,the wear on the transmission system and pitch system is very small.
