Abstract
Three-phase induction motors are used in a vast area of applications mainly due to their simplicity, ruggedness and high reliability. With recent advancement in semiconductor technologies, the use of fixed speed induction motor drive is becoming obsolete, majority of the applications now requires inverter-based drives for variable speed operation. In the study of induction motor drive operation, mathematical models are often used to simulate the steady state and transient behavior of induction motor. However, to develop such model is not a straightforward task. Knowing only the equations by themselves are not always enough without some knowledge on solving mathematical equations with the use of computer simulation software. This work presents an approach to implement the mathematical model of a Sinusoidal Pulse Width Modulation (SPWM) fed three-phase induction motor drive in MATLAB Simulink. The sub models include induction motor DQ model and a voltage source inverter (VSI) fed by SPWM signal generator. The presented model implementation is able to simulate the dynamic behavior of an induction motor operation, this would be useful for further studies on the development of induction motor drive system.
