Educational Tool for the Implementation of Electric Drives Control System with Real Time Data Exchange
Abstract:The practical implementation of a control system for an industrial electric drive involves a wide variety of well-integrated fields such as control electronics, power electronics and electric machines and drives. The learning tool presented here allows students to work with all these different fields. Furthermore, once the control system is running, this tool also provides the student with a fine-tuning system that aids understanding of the processes involved. The tuning is quite a complex task, since the whole system needs to be running in order to test the effects of successive adjustments. Traditional tuning is tedious because it is necessary to introduce the changes offline, execute the program, stop it and collect the information to be analyzed. Since the system is based on an industrial DSP, it allows an in-depth analysis of all the different phases needed to carry out the practical implementation of the drive control program on it. The low cost of this industrial DSP facilitates its use on several work benches for educational purposes. The learning system also implements a Real Time Data Exchange feature, which allows for real-time monitoring of the desired variables, such as currents, voltages and intermediate control variables.
