This paper presents MRAS speed sensorless control of induction motor using type-2 fuzzy logic controller (T2FLC). These controllers replace the PI ones, in the new MRAS strategy proposed in Benlaloui et al. (IEEE Trans Energy Convers 30(2):588–595, 2015), in order to improve the induction motor performances and robustness at low speed region. Indeed, the choice of these controllers is made because of their adaptation-based schemes which permit to handle nonlinear uncertain systems without the need of precise mathematical model required when using PI controllers. Comparative study had shown a better rejection of disturbance and high insensitivity to stator resistance compared to the PI and the T1FLC controllers. The effectiveness of the proposed speed-based T2FLC estimation method and its good robustness are validated by simulation and by experimental results.

基于二类模糊逻辑的感应电机无传感器控制改进

本文介绍了使用 2 型模糊逻辑控制器 (T2FLC) 对感应电机进行 MRAS 无速度传感器控制。在 Benlaloui 等人提出的新 MRAS 策略中，这些控制器取代了 PI 控制器。（IEEE Trans Energy Convers 30(2):588–595, 2015），以提高感应电机在低速区域的性能和鲁棒性。事实上，选择这些控制器是因为它们基于自适应的方案，允许处理非线性不确定系统，而无需使用 PI 控制器时所需的精确数学模型。对比研究表明，与 PI 和 T1FLC 控制器相比，具有更好的干扰抑制能力和对定子电阻的高度不敏感性。
