We report on recent progress in developing a computer-aided nonlinear control system analysis and design environment based on sinusoidal-input describing function (SIDF) methods. Two major additions have been made to our CAD software for nonlinear controls during 1984: a simulation-based program for generating amplitude-dependent SIDF input/output models for nonlinear plants, and a frequency-domain nonlinear compensator design package. Both of these are described. This software can treat general nonlinear systems, with no restrictions as to system order, number of nonlinearities, configuration, or nonlinearity type. An overview of the application of this software to the design of controllers for a realistic, nonlinear model of an industrial robot was presented by the author in 1984, which serves to illustrate the use of these tools. Based on the software presented, the use of SIDF-based nonlinear control system analysis and design methods is substantially easier to carry out.

The KEDDC software package for computer-aided control system design is applied to the development of control techniques for future large flexible spacecraft in a joint industry, university and government research and development project. The Operational Mobile Communications Satellite (OMSAT) proposed for the mid 1990's featuring a 44m offset-fed antenna, is used as target application. A reduced version of a 146th order high fidelity dynamics model of the satellite serves as a benchmark system. This application is demanding and forms an important performance benchmark for any software system because the high order of structural models requires the use of highly stable and efficient numerical algorithms. KEDDC has been tested on this problem for more than one year and has performed flawlessly, improving considerably the design efficiency as well as the scope of system analysis.

The engineering of software for Computer Aided Control systemsengineering (CACSE) using the concept of software tools is discussed. A set of tools is presented which will provide an infrastructure upon which a fully integrated CACSE package could be readily built. Emphasis is placed on the man-machine interface. An input and an output translator are introduced, and the interaction between them is discussed. An action manager, to control the CACSE functions of a package, is presented. The control of retained data within a package using a data manager tool is discussed.

The fact that industrial computer control systems consist more and more of complex software and hardware components and it is not possible to separate software and hardware at the beginning of the design enforces integrated development tools, supporting software development as well as hardware development. Although the developments of software components and hardware components are different at the realization level, they are interrelated in the main parts of the development, project management and maintenance. This paper illustrates the main disadvantages of using separate tools. It shows the requirements for an integrated tool and discusses the concept of the EPOS system as an example of how these requirements can be satisfied. Results of applying EPOS to industrial projects are reported, which show that quality and reliability have been improved considerably.

A conversational Fortran IV software has been built in order to facilitate the design of control systems for linear and bilinear processes. It allows simulation, analysis, observation, and control of those processes. It presents a 'menu-driven' structure and a high interactivity with animated bloc-diagrams. Two applications are presented in the field of closed loop linearization of bilinear processes: neutralization pilot plant and D. C. motor. Still in progress, this software is open to introduction of new modules.

The paper describes the role of software packages for Computer-Aided Control systems Analysis and Design (CACSAD) in control engineering education. It is shown that CACSAD-systems are becoming an indispensible tool in education because even sophisticated methods are more easily understood by the students. Realistic problems can be solved within reasonable time, especially laboratory experiments. As an example of a CACSAD-package, the KEDDC-system is described. It is shown how the KEDDC-system is introduced into the education of control engineers at the electrical engineering department of Ruhr-University, Bochum.
