In order to obtain the best power in the wind energy conversion system (WECS) of the direct-driven surface-mounted permanent magnet synchronous generator (SPMSG), active disturbance rejection control (ADRC) is introduced to track the motor speed in real time. The control algorithm provides a new design concept and an inherent robust controller component that requires very little system information. Aiming at the problem of system parameter mutation caused by internal factors and external environment changes, an adaptive controller with multi parameter identification is designed, and the disturbance caused by parameter changes is compensated in real time. The model predictive current control (MPC) technology for the sudden change of external environment is designed to accelerate the response speed of the current loop, so as to weaken the estimation of the current disturbance by the active disturbance rejection controller, and make the speed estimation more accurate. Simulation results show that the proposed control strategy is effective and satisfactory.

为了在直接驱动式表面安装永磁同步发电机（SPMSG）的风能转换系统（WECS）中获得最佳功率，引入了主动抗扰控制（ADRC）来实时跟踪电动机速度。该控制算法提供了一个新的设计概念和一个固有的鲁棒控制器组件，该组件需要很少的系统信息。针对内部因素和外部环境变化引起的系统参数突变的问题，设计了具有多参数辨识的自适应控制器，对由于参数变化引起的干扰进行了实时补偿。用于外部环境突然变化的模型预测电流控制（MPC）技术旨在提高电流环路的响应速度，从而削弱了有源干扰抑制控制器对电流干扰的估计，使速度估计更加准确。仿真结果表明，所提出的控制策略是有效和令人满意的。
