N2 - A compensation method of rotor-resistance variation in induction motor drives using high-performance slip-frequency control is considered. The method is based on a discrete-type model reference adaptive system (MRAS), and is implemented in an 8086 microprocessor. When an induction motor is driven by a controlled current source, the system is sensitivity to the rotor-resistance variation is increased. In the MRAS, the value of the rotor resistance is estimated and the slip-frequency gain is adjusted. Experimental and numerical simulation results show that even if the value of the rotor resistance varies from its nominal value, the secondary flux level is maintained constant. These results validate the compensation method.
