Design and implementation of an integrated environment for real‐time control of power electronic systems

Abstract

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

Development of an experimental system for teaching induction motors with fault detection and diagnosis capabilities

“…Damages on these bearing types can be categorized into four different types of damages [1,31,35]. The vibration frequencies due to outer bearing race are given by (7), for an inner bearing race are given by (8), for a ball defect by (9) and for a train defect by (10). …”

“…In the last years several teaching tools based on personal computers have been developed, allowing the improvement of student's motivation through computer simulation programs [7][8][9][10]. Likewise, since personal computers have become widely spread and Internet connected, several tools have appeared using this technology on distance learning schemes [11][12][13][14][15][16].…”

Design and development of an educational desktop robot R3D

“…It is acknowledged in the literature that developing a laboratory experimental setup usually costs much less compared to commercially available setups, and researchers and students gain significant experience in design and construction of real systems [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Among those laboratory experimental setups robot manipulators are considered as good examples of multiple-input multiple-output nonlinear systems that can be utilized for both control and robotics education.…”

Design of an experimental twin‐rotor multi‐input multi‐output system

“…Developing an experimental system usually costs much less compared to commercially available setups, and also, it allows students and researchers gain experience in design and construction of real systems [17][18][19][20][21][22][23][24][25][26]. According to the authors' best knowledge, there are no past works fully dedicated to design and development of a TRMS in an academic setting.…”
