LABVIEW BASED ONLINE CONTROL OF PMDC MOTOR

Abstract

The revolution of Internet-enables instrumentation is emerging as a revolution in Measurement and Automation. New standards are being developed for transmitting data and connecting instruments to the internet. The main purpose of this thesis is to design and develop a system to integrate various online experiments and able to monitor and control them over Internet using LabVIEW. LabVIEW is a graphical programming package capable of data acquisition, data analysis, data representation and real time remote control. Written communication in LabVIEW refers to communication via internet where the user can write messages to another user. Generally written communication is not found in any programming related software but LabVIEW makes this possible using internet protocol (IP). In this thesis an online system is developed which integrates several real time experiments and remote control access over Internet is provided using LabVIEW. The latest remote panel technology is used to provide the remote control access. This thesis presents the implementation of online control of Speed of DC motor with the help of LabVIEW. In this software, a Build-in Web Server application which uses Internet Protocol (IP) for developing an online transmission process between client and server. Client has a control over the set point and Server has control over the speed. With the help of internet protocol, client provides the value of set point according to which the control actions are taken by the server. A system is developed to monitored and controlled the experiment remotely over Internet using LabVIEW.
