Distributed Virtual Experiment System On Principle Of Automatic Control

The distance education based on Internet is an important way to the development of education in 21th Century .But the remote experiment on Internet becoming a big barrier for distance engineering education. The work of this thesis is a creative study and provides a realizable method on the remote experiment in the course of Principle of Automatic Control.Based on the requirement analysis,function definition and performance studying, Client/Server architecture and Browser/Web Server/Database Server architecture, consisting of Net Server, Device Server and Client was constructed. The virtual experiment based on MATLAB, remote experiment based on real equipment, inverted pendulum experiment and experiment competition on motor, inverted pendulum and compensator was designed/The system was developed with software engineering method by the steps of function analysising, synoptic designing, detailed designing, coding, testing and performance evaluating.Students can operate the remote devices via Internet.Students can code they control strategy by programmable environments(in MATLAB), then control the real remote device and get the experiment results.The system support remote control mode and can accomplish many control strategy includes PID , LQR and etc in inverted pendulum experiment.Real time remote access control is one of the new direction of computer control technique,and is under seeking and developing.This thesis begins with system design of an remote access control experiment Virtual Laboratory(VL), and accomplished remote experiments via Internet by remote control mode,at last,issues and limitations of remote access control are discussed.
