基于离散滑模模型参考自适应系统的感应电机无速度传感器驱动

By combining the high robustness of sliding-mode observer (SMO) with the adaptability of model reference adaptive system (MRAS), the sliding-mode-based MRAS can improve the speed estimation performance of speed-sensorless induction motor (IM) drives. However, the analysis of this article shows that there exists a mismatch problem between the fixed-value of SMO gains and the variable stability boun...
