Abstract :
A robust Rotor Flux Oriented Control (RFOC) requires the compensation for the effect of rotor resistance. The variation of rotor resistance due to changes in temperature or frequency degrade the performance of RFOC controller by introducing errors in the estimated flux linkage magnitude, position and the electromagnetic torque. So the compensation for the effect of rotor resistance variation then becomes necessary. This paper investigates the effect of variation of rotor resistance on RFOC performance. A method of rotor resistance estimation using a High-Gain Observer has been proposed in this paper.
