This paper proposes a new model reference adaptive system (MRAS) for the sensorless speed estimation of field-oriented induction motor (IM) drive utilizing d- and q-circuits effective impedances. The functional quantity of the MRAS, in this context, is the difference between the stator d- and q-circuits' effective working impedances. This unique structure does not require any flux computation while estimating speed. Moreover, the formulation is free from any resistance terms. The proposed estimator performs satisfactorily at all the operating points and exhibits stability in all the four quadrants of the drive's operation. The relevant stability and sensitivity studies, in this regard, are done in MATLAB/Simulink. Furthermore, the controller performance is validated experimentally by dSPACE-1103-based IM drive setup.

利用机器的 d- 和 q- 电路阻抗的基于 MRAS 的感应电机驱动速度估计

本文提出了一种新的模型参考自适应系统 (MRAS),用于利用 d 和 q 电路有效阻抗对磁场定向感应电机 (IM) 驱动器进行无传感器速度估计。在这种情况下,MRAS 的功能量是定子 d 和 q 电路的有效工作阻抗之间的差异。这种独特的结构在估计速度时不需要任何通量计算。此外,该配方没有任何阻力项。建议的估计器在所有操作点上都表现令人满意,并且在驱动器操作的所有四个象限中都表现出稳定性。在这方面,相关的稳定性和灵敏度研究是在 MATLAB/Simulink 中完成的。此外,控制器性能通过基于 dSPACE-1103 的 IM 驱动器设置进行了实验验证。
