Simulink/MATLAB Dynamic Induction Motor Model for use in Undergraduate Electric Machines and Power Electronics Courses

A dynamic model of the induction motor developed using Simulink / MATLAB that is beneficial for use in undergraduate electric machines and power electronics courses is presented. The model can be used to study the dynamic behavior of the induction motor, or can be used in various motor-drive topologies with minor modifications. The motor model presented is based on the T-type d-q model of the induction motor. A block model approach is used in the construction of the motor model that will allow students to resolve reference frame theory issues. The model developed is intuitive, easy to use, and allows all motor parameters to be easily accessed for monitoring and comparison purposes. The model presented is capable of being used with various inverter topologies and PWM schemes with minor modifications.
