基于自适应饱和控制器的永磁同步电机直接转矩控制

This paper proposes a novel direct torque control (DTC) scheme for permanent-magnet synchronous motor (PMSM) drives using a relatively low sampling frequency. Unlike the conventional DTC in which a single voltage vector is selected according to the outputs of the hysteresis controllers, the proposed DTC uses nonlinear adaptive-midpoint saturation controllers to regulate the torque and flux trackin...
