| Abstract |
This paper presents a real-time temperature monitoring technique for the induction machine.
The proposed method is based on the estimation of the stator and rotor electrical resistances by an
extended Kalman filter. To avoid the observability problems of the electrical model, we propose to
add a thermal model of the machine. An instrumented test board is presented and the difficulties of the
identification of the thermal model are discussed. The first experimental results show the efficiency of
the extended Kalman filter when the sensitivity of the stator and rotor resistances is sufficient (low
speed and high torque). They also show the necessity to use an adequate thermal model to increase the
accuracy of the temperature estimations. |
