In this paper, a robust vector control sensorless based on three Active Disturbance Rejection Controllers (ADRC) for an induction motor fed by a five-level cascaded H-bridge was developed. The estimation of rotor position is achieved using a Luenberger estimator. The proposed model considers the disturbances and the inaccuracies of the system and compensates them using the extended state observer of ADRC. Moreover, a five-level cascaded H-bridge inverter is the best topology to minimize the torque ripples and to improve the current output of IMunder control. The suggested control system was simulated under different conditions using MATLAB-Simulink. The results demonstrate the effectiveness and the robustness of the proposed system against disturbances such as variations of parameters and load torque.

面向级联的五电平H桥逆变器无源感应电动机的有源干扰抑制控制

在本文中,基于三级主动干扰抑制控制器(ADRC)的五级级联H桥馈送的感应电动机,开发了一种鲁棒的矢量控制无传感器。转子位置的估计是使用Luenberger估计器实现的。所提出的模型考虑了系统的干扰和不准确性,并使用ADRC的扩展状态观测器对其进行了补偿。此外,五电平级联的H桥逆变器是最佳的拓扑,可以最大程度地减小转矩脉动并提高IMunder控制下的电流输出。所建议的控制系统是使用MATLAB-Simulink在不同条件下进行仿真的。结果证明了所提出的系统针对诸如参数和负载转矩的变化的干扰的有效性和鲁棒性。
