Abstract:
In this paper, a detailed study on the Model Referenee Adaplive Controller( MRAC ) ulilizing thereaetive power for the veetor control of molor drive is presented. The model of speed estimation on the MRACbased reaetive power is building. lt eliminates the elfeet of the stator resistanee’s change, and is free of caleu.lus items, and improves the aeeuracy of speed estimation, dynamie performanee and stability enhaneement olthe eontrol system. That has one simulation analysis on the loading, step response and ramp response of themotor. Simulation results have been presented to eonfirm that Veelor Controlled Induetion Motor based MRACutilizing the reaelive power has good eonvergenee and stability. The results reveal that the estimated speed fol.lows the aetual with good aecuraey, and has satisfactory perforanee around zero erossing.Key words : induetion motor, veetor eontrol, model referenee adaplive controller, reaelive power
