Simulation of indirect field-oriented induction motor drive system using Matlab-Simulink software package

Abstract EN

-This paper presents a methodolgy for computational modeling of the indirect field-oriented ( IFO) induction motor drive system.

The numerical model of the squirrel-cage, three-phase induction motor is represented as a system of differential equations.

In order to study the performance of the system a simulation program was implemented using Matlab/Simulink software package.

The induction motor is supplied by a space vector Pulse Width Modulation (PWM) inverter which is implemented also by the same simulation program.

The dynamic curves of the motor phase current, voltage, speed and electromagnetic torque during starting and steady-state conditions are ploted.

The step change loading effects on the stationary reference frame stator current components, synchronous rotating frame stator current components, electromagnetic torque and stationary reference frame rotor flux components are observed.
