An Integrated Virtual Learning System for the Development of Motor Drive Systems

This paper describes the basic concept of an integrated virtual learning system as an instructional tool for the development of DSP-based control schemes for motor drive applications. The system is comprised of a graphical user interface (GUI) front-end and a hardware-inthe-loop custom digital signal processor (DSP) for rapid prototyping and efficient testing of digital control algorithms. The circuit design and control algorithm development of a pulse width modulation (PWM) voltage source inverter (VSI) for three-phase brushless dc (BLDC) motor control applications is used to describe the functions of the system. It is shown that the virtual learning system provides a cost-effective learning tool for students or engineers in training and can serve as a supplement to a conventional laboratory based system.
