| 摘 要： | 针对目前中频发电机在满载时，采用开环控制运行下，系统抗干扰能力较差的问题，提出了一种基于自抗扰控制器（ADRC）的逆变器控制方法。自抗扰控制器完全独立于被控对象的具体数学模型，把系统所有不确定因素与外部扰动归结于系统总扰动，通过扩张状态观测器（ESO）对扰动进行观测，然后利用非线性状态误差反馈律（NLSEF）进行补偿。仿真和实验结果表明，所设计的自抗扰控制器能有效抑制负载及永磁发电机的干扰，具有良好的动态特性及较强的鲁棒性。

| Abstract: | An active disturbance rejection control （ADRC） method was proposed to control the non- linear open-loop state of the inverter of a medium-frequency permanent magnet generator under full load. The active disturbance rejection controller is completely independent of the specific mathemati- cal model of the controlled object. All the disturbance factors were regarded as the disturbance to the system, which was dynamically observed by extended state observer （ESO） and was compensated via the nonlinear state error feedback （NLSEF）. The simulation and experimental results show that the active disturbance rejection control technique can effectively restrain the disturbance of load and the permanent magnet generator with favourable dynamic characteristics and robustness. |
