Abstract :
Flux and rotor speed observer is required for sensorless control of induction motor. This paper shows some different methods of estimation. There are two flux and three rotor speed estimators, which were chosen from the most promising methods presented in literature. Description of control system with TMS320F2812 DSP and experimental results of proposed algorithms are given too
