Abstract: Designed a remote experiment system based on 3-DOF helicopter. Used the pattern of Browser/Server, WEB server control the 3-DOF helicopter remotely through the Matlab/Simulink Real-Time Workshop run at the local server. Users who have a computer access the internet can do a remote experiment by their browser. They can finish lots of works by the system such as know the characteristics of 3-DOF helicopter, learn how to use Matlab/Simulink Real-Time Workshop, make new algorithms and test them and so on.
