FIELD ORIENTED SPEED CONTROL OF INDUCTION MOTOR DRIVES
This paper presents the field oriented control of a three phase induction motor up to base speed to investigate the improved performances of an induction motor driven by a PI controller by using a commercially available software package Matlab/Simulink. The concept of field – orientated control (FOC), an indirect method of vector control method, has been selected to be the motion control technique because it produces controlled results that have a better dynamic response to torque variations in a wider speed range compared to other scalar methods. A PI type speed controller has been designed to investigate the performance of IM drives.
