| 摘 要： | 根据自抗扰控制器的原理,设计了风力发电系统的最大风能捕获控制器。将风能转矩的不确定性与系统的摩擦不确定性统一视为系统的未知干扰,通过扩张状态观测器来估计,然后利用非线性反馈控制律进行补偿,使系统的控制律仅与系统的给定输入和输出有关,减少控制过程中的检测量,将复杂的控制过程简化。通过非线性跟踪一微分器的适当设计,实现了最大风能捕获,证明控制策略的可行性,同时通过参数的改变,验证了该控制方法的具有很强的适应性和鲁棒性。

| Abstract: | A controller for maximum wind energy capture of wind power system according to the theory of auto disturbance rejection controller has been presented. The uncertainties in the torque of turbine and friction are both considered as the unknown disturbance to the system. The expending state observer can evaluate the unknown disturbance. With the nonlinear state error feedback control law, the disturbance can be compensated. The control law has only relationship with the reference and the output. So the control is simplified with fewer variables detected. The maximum energy capture is achieved through the design of tracking-differentiator. The feasibility, adaptability and robust of the control is testified by this result. |
