Abstract

The vector control of ac drives has been broadly used in high performance control system. Indirect field oriented control (IFOC) is one of the most efficient vector control of induction motor due to the simplicity of designing and construction. This paper presents the performances of three phase induction motors using space vector pulse width modulation (SVPWM) scheme. The SVPWM system is entrenched with the two control loops, the inner current control loop and the outer speed control loop using PID controller. Both systems were run and tested using MATLAB/SIMULINK software. The simulation results demonstrate that the SVPWM can improve the feature of the stator current and reduce the torque ripple while keeping the other performance characteristics of the system.
