    摘 要:针对永磁同步风力发电系统 (PMWS) 存在的非线性、参数摄动、不确定性、多干扰等问题,采用一种基于最佳叶尖速比的最大功率跟踪控制方法,将最大功率捕获问题转换为最佳速度跟踪问题,分别针对速度环和电流环进行自抗扰控制器的设计;考虑到大干扰环境中,系统受内、外扰动的影响,转速跟踪精度有所下降,为提高控制精度和鲁棒性,针对速度环设计了一种基于扰动观测的降阶自抗扰控制器。通过扰动观测器对系统的总干扰进行在线观测,然后利用自抗扰控制器进行干扰补偿,从而提高转速的跟踪能力。仿真结果验证了所设计的复合控制器能有效地抑制系统扰动对转速的影响,提高了系统的鲁棒性和抗干扰性能。

    Abstract: This study proposed an improved ADRC by considering the problem of nonlinearity, parameter perturbation, uncertainty, and multi-disturbance in permanent magnet synchronous wind power generation systems (PMWS). It employed the maximum power tracking control method based on the optimum tip speed ratio to transform the maximum power acquisition problem into the optimal speed tracking problem and designed the ADRC for the speed loop and current loop. The speed tracking accuracy of the wind-driven generator might decrease because the system suffered internal and external disturbance in the maximum interference environment. A reduced-order ADRC based on disturbance observation was designed for the speed loop to improve the control accuracy and robustness. The disturbance observer observed the total disturbances of the system online and used the active disturbance rejection controller to implement disturbance compensation and improve the speed tracking ability. The simulation results verified the designed composite controller could help control the influence of the system disturbance on rotational speed.
    Key words: disturbance observation; auto disturbance rejection controller; wind power generation system; power tracking; nonlinear
