Speed Control Of A Three Phase Induction Motor Using Field Oriented Control

Eng. Mohamed Hussein, Dr. Mahfooz E. Shalaby, Dr. Hamdy A.M. Shatla, Dr. Amr Refky, Dept. of Electrical Engineering Al-Azhar University Cairo, Egypt Abstract—Induction Motors are rugged, robust and widely used in industrial applications. Field oriented control (FOC) or Vector control is an efficient method to control either the speed or the torque or both of the three phase Induction motor. FOC converts the complex stator currents into two orthogonal components, one of which is responsible for speed control, and the other for the electromagnetic torque control, similar to DC machines. FOC has greater stability and capable of fast torque response and accurate speed control. This research explains the concept of FOC and its simulation rather than experimental...
