A new Matlab/Simulink based simulation toolbox for studying and designing induction motor field oriented control schemes is proposed in this article. It has advantages over other previous works published since it is modular, flexible, interactive, easy to use, and the results are closer to the experimental ones because it takes into account real complex effects, such as: motor core saturation, parameter variations with the speed and temperature, sensor signal digital processing, and inverter real voltage waveforms. These results has been successfully applied in teaching undergraduate and graduate courses at the authors' universities for building, identification and characterization of diverse control schemes, analysis of parameter effects, and design and test of new controllers for field oriented control schemes in induction motors. Beside the theoretical and computational basis of the toolbox, simulation results of an indirect field oriented control current regulated pulse width modulation scheme are presented in the article as example.
