基于有源磁链或转矩注入的直接转矩控制感应电机定子温度估计

This paper proposes two thermal monitoring methods for induction machines with direct torque control (DTC). The stator resistance Rs is used as a direct indicator of average winding temperature and is estimated via a dc current offset in the stator winding. In a DTC drive system, the major challenge is how to excite the dc current offset via the only existing flux and torque control loops. The qua...
