this paper presents the structure of a multiuser system for the teaching and practice of analysis and design of control devices. the system uses the software matlab as a computer tool support. several users can have access to the physical devices connected to a central computer server and the connection between the users and the server is done using serial ports. the proposed system uses only one data acquisition card and a dynamic system, optimizing in this way the available resources. the paper also presents some characteristics and applications of the proposed system, demonstrating its simplicity and versatility.
