On the optimization of the rotor flux vector control used in induction motors drive systems

The paper presents an optimization of an indirect vector control strategy for induction motor drives. Based on the mathematic model of the induction motor which considers the iron loss resistance, a control algorithm has been conceived to reduce the difference between the measured and estimated torques. Two cases are presented in the paper. In the first case the iron loss resistance is neglected in the control algorithm, but it is considered in the second case. The indirect vector control algorithm was implemented on a dSPACE DS 1104 platform controlling an inverter fed 2.2 kW induction motor.
