An integrated virtual learning system for the development of motor drive systems

In this article, an integrated lab environment for the electrical engineering education is presented which includes hardware and software for the modeling, simulation and control of multilevel inverters. A five-level cascade inverter is designed and implemented which is an educational platform for the students to test different pulse width modulation (PWM) techniques and verify simulation results. The integrated environment is based on Matlab together with dSPACE. Sinusoidal PWM (SPWM) and Selected Harmonic Elimination PWM (SHEPWM) blocks are constructed in Matlab/Simulink and converted to C code using Matlab/Real-Time Workshop. C codes are sent to dSPACE's DS1103 digital signal processor (DSP) via dSPACE/Real-Time Interface software. Voltages with variable frequency and amplitude obtained from SPWM and SHEPWM techniques are applied to an induction motor. Simulation and experimental results are visualized on the designed graphical user interface (GUI). The GUI is developed using dSPACE's ControlDesk software. ß

“…By simulation, it is easier and economical to examine the effect of parameters on the system behavior. The system design process can thus be reduced with the simulations [2,3].…”

“…Such systems require an actual hardware setup and a set of laboratory measurement systems that are sometimes costly to build and difficult to maintain. For safety and security reasons, access to the Correspondence to E. Tanyildizi laboratory-based system is usually limited to a certain time and can only be given in the presence of a local facilitator [3].…”

Engineering education can reach the desired level if practical laboratory works are given together with the theory. In electrical engineering education, if foundation costs are considered the electrical machine labs become very important. Due to the increasing number of students accessing the university educational structures, the cost of laboratories for didactical electric machine applications is going to be very high. In this study, virtual laboratory, which is found to have wide application field in recent years, is introduced. For this purpose, a virtual electrical machine lab for electrical engineering lab courses is developed. An example of application was presented for the control of synchronous motor and no-load and blocked rotor test of synchronous generator. Moreover, this study explores the learning effect related to different learning styles of web-based virtual lab that has developed in electric engineering students.

“…Therefore, computer simulations and dedicated software become very important. Many colleges are now developing educational tools for: fuzzy logic control of electrical machines [18,19], effective use of multimedia for teaching of electromagnetic education [20], virtual learning system for DSP-based control system of motor drives [21,22], and neural network control of electrical drives [23]. The well known software package, MATLABSimulink developed by Mathworks, Inc., offers neural-fuzzy toolboxes, in addition to many other toolboxes.…”

Neural and fuzzy courses are widely offered at graduate and undergraduate level due to the successful applications of neural and fuzzy control to nonlinear and unmodeled dynamic systems, including electrical drives. However, teaching students a neurofuzzy controlled electrical drive in a laboratory environment is often difficult for schools with limited access to expensive equipment facilities. Therefore, computer simulations and dedicated software are needed to assist the students in visualizing the concepts and to provide graphical feedback during the learning process. In this article, an educational software is proposed for the neuro-fuzzy control of induction machine drives. The tool helps students learn the application of neuro-fuzzy control of electrical drives. The software has a flexible structure and graphical user interface. The neuro-fuzzy architecture, the motor and load parameters can be easily changed in the developed software. Neuro-fuzzy control performance of induction motors can be monitored graphically for various control structures and current controllers. ß
