Application of CAD in modeling, identification and control of industrial and large scale, nontechnical processes

This paper gives a short description of the CAD facilities available at the University of Trondheim, Division of Engineering Cybernetics and presents experiences and results from an operation period of almost ten years. The CAD facilities consist of an interactive program library, CYPROS, which contains general programs for simulation, identification, parameter estimation and control system design and a specialized CAD package for handling large scale systems. The programming language is standard Fortran IV and the packages are implemented on a medium size computer system where the user-program communication is based upon numerical terminals and video color graphics.
