Induction motors field oriented control based on averaged parameters

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