Remote control laboratory for DSP-controlled induction motor drives

This article presents an Internet‐based remote laboratory for digital signal processor (DSP)‐controlled induction motor (IM) drive. The remote experimental rig uses MATLAB/Simulink compatible dSPACE DS1104 signal processor to realize the control algorithm, current control, and PWM modulation. MATLAB Real‐Time Workshop (RTW) environment provides the real‐time operation using a PC and I/O boards and, therefore, application files required for conducting the experiment in laboratory environment can be prepared with the RTW and dSPACE real‐time interface (RTI). Also a graphical‐user interface can be designed using the dSPACE ControlDesk Developer (CDD). However, for implementation of remote laboratory, interface software between local application and remote users should be developed, since the MATLAB Web Server (MWS) does not allow online access to some hardware such as DS1104 used in this study. For this purpose, an interface using the Python code is developed for remote automation of the ControlDesk. Furthermore, server–client communication software with Delphi programming language is developed for remote implementation of the experiment. Using the user‐friendly interface, the Internet‐based remote laboratory allows the students to conduct the experiment by changing the predefined control parameters online or uploading the controller designed by the user and then to observe system responses in numerical, graphical, or video format on the remote computer.

Technology policies in education: Turkey and several other countries / Eğitimde teknoloji politikaları: Türkiye ve bazı ülkeler

Technology’s development and being widespread, it’s positive effects on education caused information technologies to be used in the academic process. And countries are under the obligation of keeping the education facilities up to date in an appropriate way to provide the necessities of the age. As a result of these necessities, technology policies are being developed in academics. In this study, a research has been conducted to analyze the case by researching Turkey’s and some other countries’ already active or due to get activated projects. At the conclusion of the study, the student’s getting an education with the latest technology, equality of opportunities in education, effective use of information technologies in education, providing the maximum integration of information technology devices in education are amongst the aims of the project. Introducing the project was generally done by preparing a web page. With technology policies, laptop computers and tablet computers were given to students. Various trainings were organized to provide effective use of technology in education. In the research, the conclusion was reached that maintainability of countries’ developed technology policies in education by proving hardware and software units in education facilities was not stated clearly.
