Modelling a Vector Controlled Induction Motor in Simulink

A workflow to model an electric motor drive system with a control system in Simulink is presented. The induction motor (IM) is modelled using an equivalent circuit based on the space-vector theory in the stationary reference frame. The motor is controlled using the classical indirect vector control implemented in the rotor flux reference frame that utilizes an ideal converter and modulator. The presented system model can be used as a basis for teaching electrical drives, particularly in the context of learning by doing where the goal is to learn new things using a practical approach. The following approach links the space vector theory to practice and helps students to understand the importance and the value of the theory.
