the design of a generic virtual instrument used for real-time experimentation purposes at Polytechnic Universityâ„¢s control engineering laboratory in a remote-access environment. These instruments can be freely downloaded and the remote user can access the laboratory facilities from anywhere and anytime. The philosophy behind our Internet-accessed remote laboratory is based on a client/server computer configuration. The server, situated near the experiment, transfers to it the received command signals transmitted by the client. The client locally computes the command signal based on the reference waveform and the transmitted system response. The remote user can select the transmission protocol, switch between asynchronous and synchronous sampling, use either a batch or a recursive data transfer mode, and view the experimental testbed. Our approach is distinct from others since it can offer more flexibility and responsibility to the client-side, since the remote user compiles, and executes locally the controller. Issues concerned with networkâ„¢s reliability, dynamic delay factor caused by the Internets traffic, concurrent user-access, and limited computing power have been addressed. The designed set of experiments is the first step towards our remote control laboratory

INTERNET-BASED CLIENT/SERVER VIRTUAL INSTRUMENT DESIGNS FOR
REAL-TIME REMOTE-ACCESS CONTROL ENGINEERING LABORATORY
a generic virtual instrument used for real-time experimentation purposes is described here. A remote user can access the laboratory facilities. the experiments are emulated via a fast processor and the experimental data can be accessed by the students over a computer network.
a client/server computer configuration is the base of this . The server, situated near the experiment, receives the request from the client and responds to it. The command signal is computed by the client based on the reference waveform .
Client Enhanced Internet-based Remote Laboratory
All the features of the virtual laboratory are supported also it provides the user with additional options by allowing more responsibility on the client side. who implement and execute the controller can be chosen by the client. This ha many advantages:
- using computationally powerful clients for implementation of complex control
laws
-advanced control laws can be implemented despite significant limitations on the server-side
- implemented controller-code privacy.
