We present a program package which includes alternative routines to compute hierarchical and decentralized control laws together with a proposed interactive multicriteria optimal control algorithm to consider appropriately non-conmensurable and conflicting criteria at different levels. The package includes an interpreter, based on fuzzy set theory, which permits performing the designer's interaction in the algorithm in a qualitative linguistic way. The package is written in Pascal and permits a low cost implementation in microcomputers with the CP/M operating system. We present an example of two area megawatt frequency control which illustrates the design procedure.

A newly developed interactive graphics CAD package for linear multivariable controlsystems in the parameter space framework is presented. By direct geometric interpretation of stability, performance, robustness, integrity, actuator constraints, and other practically important objectives, the 3D capabilities of high-performance interactive computer graphics systems can be employed to design directly in the space of free system parameters. Intelligent strategies make it possible to access high-dimensional parameter spaces by decompositions or heuristic search for display subspaces. The structure and computer realization of the package is discussed with emphasis on the unique user-computer interaction features. design examples show application of the main techniques for up to 15-dimensional parameter spaces and illustrate the potential as an engineering analysis and design environment.

An interactive system called SYSLAB for analysis and design of linear multivariable controlsystems inthe state space is described. It is developed on the basis of MATLAB - a powerful interactive language for matrix computations which implements high quality software for solving matrix problems. SYSLAB makes possible to solve the basic problems of the analysis and design of linear multivariable controlsystems: stability analysis, investigation of the controllability/observability and reduction into canonical forms, pole assignment and synthesis of optical linear systems. Only algorithms that are proved numerically stably are implemented. SYSLAB is written in Fortran and is fully portable.

A man-machine interface well suited for computeraidedcontrolsystems design (CACSD) is presented. We start with presenting the general command-driven interface of IMPACT, an interactive CACSD-package presently implemented in the new programming language Ada. We elaborate on its versatile macro concept (functions/procedures). The interface of IMPACT uses a syntax similar to that of Ada and is flexible enough for the algorithmic type of problems found in CACSD. A facility of concurrent sessions not unlike those found on many modern workstations is presented. The macro and session concepts are combined to form the 'query' option, a feature intended to be used to guide the inexperienced user in a more controlled manner.

The fact that industrial computercontrolsystems 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.

An integrated computer-aided-designsystem to simulate, analyze, and design robotic systems is presented. This system allows the engineer to derive design parameters from functional requirements, develop a design from these parameters, and perform all analysis (including dynamic and controlsystem analysis) totally on the computer before hardware is built. The software and hardware architecture of the system is described.

The authors discuss the requirements and design of an expert-system-controlled adaptive dialogue facility for computer-aidedcontrolsystemdesign facilities. The facility detects the degree of familiarity of a user of a control CAD (computer-aideddesign) package by monitoring the correctness and speed of the user's actions and the amount of usage of online help and adjusts the nature of the dialogue accordingly.

Some issues pertaining to computer-aidedcontrolsystemdesign (CACSD) are discussed. A critique of current methodologies is given in terms of realistic requirements. This leads to a natural requirement for software tool-based CACSD systems. Emphasis is given to development of tool-based systems in a Unix environment.

The paper deals with the improvement of system identification procedures by interactions between the user and the computer. The basic identification algorithms are discussed with respect to the necessity of dialog at some places of the procedure and the efficiency of that approach for model and parameter estimation. All referred problems are implemented in the interactive software system named INSOF-I. The conception and considerations for its hierarchical structure are given. All ideas of the man-machine interaction supported by the protocol and graphical output of INSOF-I are demonstrated by the generalized least squares estimation method.

This paper presents a design method for simultaneous optimization of a large number of controller and plant parameters of high-order linear time-invariant systems. User-friendly supervision and control of several design objectives is achieved through an interactive graphics-supported design process. The application of the design package for optimal matching of construction and controller parameters is demonstrated taking as an example a vehicle model with actively controlled tandem wheel suspension.
