风速在额定风速以上时,变桨距风力发电机组的控制目的是通过桨距角的调节将风电系统的输出功率限制在额定值。针对风电系统二阶模型进行精确反馈线性化,将逆推设计方法和自适应以及滑模变结构控制有机结合,获得了一种保证该类系统全局渐近稳定的自适应反演滑模控制律。根据该设计结果,得到此风电系统的自适应反演滑模变桨控制器,并对所设计控制器进行仿真,结果表明:该控制器能有效、迅速地稳定不确定风电系统,性能很好。
Wind speed above rated wind speed, pitch wind turbine control objective is to limit the output power of the wind power system rated at a pitch angle. For the linear feedback of the second-order model of wind power system, the inverse design method and the adaptive control of sliding mode control are combined organically to obtain an adaptive inverse sliding mode control law to ensure global asymptotic stability of the system. . According to the design results, the adaptive inverse sliding mode controller of the wind power system is obtained and the controller is simulated. The results show that the controller can effectively and quickly stabilize the uncertain wind power system and has good performance .
