CES - A Workstation Environment for Computer-aided Design in Control Systems

Abstract

This paper describes CES, a Control Engineering workStation which provides an integrated graphical environment for the computer-aided design of control systems. CES provides user-friendly tools for the pre-processing of input information in graphical form, together with facilities for accessing existing packages for the computer-aided design of control systems. Tools for the input of graphical representations of systems in the form of block diagrams and signal flow graphs are described, together with facilities for the input of associated mathematical text in natural form. Tools for the symbolic reduction of a graphical representation, transformations between one type of graphical representation and another and for the automatic layout of graphical representations from topological data are also described. The requirements for interfacing CES to software packages for the computer-aided design of control systems are discussed.
