Virtual Lab: Remote Access and Speed Control of DC Motor using WardLeonard System
Abstract
Limited resources and requirement of regular maintenance of equipment in traditional
laboratory supports idea of Web-accessible laboratories which provides facility of online
experimentation on real processes. The objective of this project is to demonstrate the realtime web-based laboratory experiment conduction by accessing the laboratory set-up from a
remote location and measure the experimental parameters by generating the control
commands at a distant client. This architecture is developed to demonstrate the remote
learning process using graphical programming tool LabVIEWTM10. The principle behind the
implementation of remote laboratory session is to deliver the image of the control panel of
the virtual Instruments to the remote client. The experimental hardware is linked to the webserver by Data acquisition (DAQ) interface card. The proof of concept has been demonstrated
by controlling the speed of DC motor using Ward-Leonard method and recording the
measurements using Virtual Instruments.
