Induction motors field oriented control based on averagedparameters

摘要

This paper exposes the performance of field oriented control forinduction motors drives based on average motor parameters, rather thanindividual ones. The average parameters for a group of industrial motorsof small size (7.5 kW, 50 Hz, 4 poles, 380 V) have been evaluated, withreference to field oriented control. Averaged field oriented controlsbased on the mean values of motors parameters, obtained by statisticalanalysis or from motor data sheets, have been set up. Test criteria,chosen to evaluate the control performance, are presented and discussed
