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.

The framework of the support system for elementary technological unit (ETU) design is presented. The ETU is a part of chemical installation which works on the base of one reactor. The problem of working out the concept of the ETU is discussed. The artificial intelligence production system and the branch and bound method as a base of system algorithm were chosen. The system will be hierarchical and composed of: a structure generator and process unit evaluation module. The first says 'what is to be done', the second 'how it can be done'. The alternate work of those parts is shown. Two-dimensional quality coefficient energy/investments from cost engineering was chosen. The use of the system as a part of an economic decision support system is proposed.

A description is given of a computer-aidedcontrol environment being developed in Smalltalk. A conceptual model of systems is used as the basis for a date model within the object-oriented programming environment provided by Smalltalk. It is shown how object-oriented programming can be used to provide a user interface to existing design and simulation packages. The object-oriented data model provides a simple means of integrating these packages.

The work contains a description of an interactive program package ANA which can be used as a tool for analysis and design of systemcontrol. It is designed for linear, time invariant, univariable or multivariable, continuous or discrete systems. The usefulness of the package is shown through the interactiveness of programming which enables fast and simple work for different users which are familiar with system theory. For communication the simplest dialogues are used but they are not tedious and time consuming for experienced users because indirect running (BATCH) of the package is possible to repeat the whole design procedure with changed parameters or to repeat a part of the procedure and then proceed in direct way. Program package is built modularly so that its development is easy. All programs are written in FORTRAN-IV which enables simple transfer of the package to different computer configurations. In the future some additional extensions are foreseen like introducing digital simulation language in the package and some other approaches to the controller design. This will ensure greater capabilities of the package also in the sense of nonlinear systems treatment.

This paper deals with an interactive system for simulation, identification and control of linear systems described by state-space or transfer-functions, in a continuous, discrete or sampled representation. Based upon a university prototype, SIRENA plus has now reached an industrial quality level. Written in FORTRAN-77, this system has been implemented on a large variety of computers. Robustness has been ensured by a high quality mathematical software developed from and in a similar way as some well known libraries (Harwell, Nats projects, Matlab, . . . ). Its modular structure (700 routines/60,000 lines) enhances its maintainability and evolution. The system is user friendly, with an on-line help and error checking, files saving options, and on-line graphical features. Commands are prompted adaptively according to the working context and to the user skillness.

The authors have been teaching for 5 years fundamentals of industrial robots and handling devices for students of mechanical engineering, electrical engineering as well as applied mathematics and computer sciences. These fundamentals include mechanics, model building, simulation and control. For the practical education in laboratory courses two personal computers, a hydraulic-driven robot and a hybrid computersystem for simulations is available. At a lower level the students solve the kinematic and kinetic equations with the personal computer for different structures of robots. The hybrid computer is applied for simulations of the controlled robot. The hydraulic robot can be controlled by means of a control box with pushbuttons for movements. Another programming possibility for robot movements consists of using a special language which is different for each robot. The control box of our robot is replaced by a personal computer for advanced studies. For all laboratory experiments the necessary software packages are written in dialog form like a CAD system.

The paper presents an interactive package for the identification of the elements of a control loop. This includes not only the dynamic behaviour of the process, but also the static behaviour of the process and the controller and the static nonlinear behavior of the sensors. The program contains subpackages for model estimation, parameter estimation and curve fitting. Model evaluation and parameter estimation are necessary for the simulation of processes and controllers in order to develop appropriate control strategies. Although ARMAX models are chosen for most of the identification techniques, one algorithm allows the estimation of continuous system parameters. Curve fitting is needed for the static behaviour of processes and for the nonlinear behaviour of industrial sensors. The program is interactive and offers many graphical possibilities such as x-y engineering plots and three-dimensional plots.
