A DTC-model for Electrical Drives Teaching

Effective and educative induction motor (IM) Direct Torque Control (DTC) simulation with Simulink software is presented. Motor model is realized in stator reference frame and the inverter modulation is controlled with DTC principle. Inverter non-idealities are neglected and inductances and resistances of the motor are considered as constants. The DTC model is created with multiple subsystems which allows to break down the whole control system to smaller and easily understandable parts. This way the basics of the DTC can be comprehended easier, and the model used in the education of electrical drives. In addition, the Simulink model utilizes only the basic Simulink blocks, so no additional libraries are required.
