Abstract

In this work, an adaptive observer is applied to each induction motor. Stator currents, rotor fluxes and motor speeds of each motor are estimated by an adaptive observer. The multiple motor drive system is made more stable by applying the average and difference of these estimated values to field oriented control. This paper shows that proposed method mentioned above is effective by using simulation and experimental results.
