Abstract :
The stator resistance variation will deteriorate the performance of a direct torque controlled (DTC) drive, and therefore is a significant issue for DTC. In order to solve this issue, a novel stator resistance estimator for an interior permanent magnet synchronous machine (IPMSM) based on stator current has been proposed and evaluated. The advantage of this scheme is that it needs the current signals only. By means of comparing the actual current and the reference current, the change of stator resistance can be tracked. Modeling and experimental results show the effectiveness of the new method.
