Design of Man Machine Interface for Real-Time Online Control of DC Drives

Automation system developers focus on Internet based control due to availability of several tools to integrate the hardware control equipment with World Wide Web. The paper describes the development of web interface to a DC drive using Virtual Instrumentation tools. The custom electrical hardware serves as the web interface, where it supports various features to control and measure the parameters of the electrical machine remotely. The novel techniques have been used to interface the low power data acquisition system with the DC machine driven by the AC power line supply. The system uses the client-server architecture to access the virtual instruments through the web browser. The developed system allows the remote control and measure of electrical parameters though the Internet.
