基于速度自适应磁链观测器的感应电机无传感器驱动弱磁区预测转矩控制策略

In general, flux-weakening operation of induction motor (IM) drive to achieve control above the rated speed is challenging. The challenge further aggravates if the drive becomes speed sensorless. This article primarily focuses on the flux-weakening operation of adaptive flux observer-based speed sensorless IM drive working under a promising predictive torque control (PTC) regime. The flux-weakenin...
