This paper describes a course in Cybernetics and modelling of systems. Some of the course provides experience in testing parts of real systems, and identifying their dynamic characteristics. Some of this work involves the use of personal computers with suitable analog-digital conversion interfaces, so that students get experience with many uses of computers. In 1979, when many micros deployed in one teaching laboratory became a possibility, a teaching package, called Cycloid, was developed to run on the RM 380Z. The main objective of Cycloid is to reinforce lectures on controlsystems given to 2nd and 3rd year BSc courses in Cybernetics. It provides interactive design experience of single-input single-output linear systems, highlighting the correlation between frequency and time domain responses for quite a range of servo and process controlsystems.

In this paper an overview is given of some of the current research activities on robust identification of uncertain systems. This field deals with identification of nominal models, estimation of uncertainty models, and validation of uncertainty models for the purpose of robust control design. Special attention is given to issues of black-box estimation of uncertainty models.

Traveller and driver information systems are usually applied on motorway and high capacity truck road networks, providing information on accidents, queues and congestion levels and recommending diversion routes where appropriate. Using Edinburgh as a case study, this paper describes how traveller information and controlsystems can be designed as part of an integrated approach to reducing traffic congestion in urban areas. The Edinburgh system illustrates how traveller information and controlsystems can be applied in an integrated manner within a complex urban environment to tackle the problem of traffic congestion.

Torbert proposed eight stages of personal development that an individual manager may go through based on ideas of ego development in the field of psychology. He extended these stages to cover the development of the organisations. In this article, an attempt is made to extend such thinking to the development of information systems.

Improving design collaboration occurs not through increasing communication, but by providing effective communication. A cognitive artefact can provide this coordination, channeling information to designers in the form that they require. However, one needs to understand how design information is cognitively, socially and culturally encoded and transmitted. Examples of how this can occur and suggestions for CA redesign are given in this paper.

Information on a software package developed for use by students in a first course in controlsystems are presented. The flexibility provided by the package is found satisfactory for many industrial applications. Many users of control engineering software are not using the software continuously and therefore any approaches which make the software easier to use are particularly useful. Additional packages are developed to study such topics as simple aspects of nonlinear control, model reduction and PID controller design.

Automated fault diagnosis of engineering systems and industrial processes is an active research area in both AI and controlsystems engineering. Both fields use model obtained from principled system structure and behavior knowledge to make predictions about behavior. An architecture for parameter identification, based on qualitative modeling and reasoning techniques is presented. This is used as the basis for a time constrained model based diagnosis system. Also outlined is the QPID (Qualitative parameter identification for diagnosis) architecture.

The proceedings contains 9 papers from the ieeE colloquium on human-computer interface design for multimedia electronic books, organized by Professional groups C5 (Human-computer interaction) and C10 (Consumer and domestic systems), held at the Savoy Place on February 22, 1995. Topics discussed include the design, evaluation and applications of electronic books;user interfaces;and information dissemination, retrieval and analysis.

An integrated package has been developed for the simulation and physical testing of discrete controlsystems running under PC-MATLAB for DOS. The system is simple and has very modest hardware and software requirements. controllers can be designed and tested using the simulator and then immediately implemented with no editing required to interface them with the physical plant. Only the controller function needs to be written as a new code since all data acquisition and file storage is automatically accomplished.

The development of the FOX environmental control system is described and some of the benefits of the adopted design approach are outlined. Since its launching in September of 1994, over 200 systems have been installed. Reports from users and carers about FOX have been highly complimentary. Specific benefits noted include the reliability of the system, the efficiency and kindness of technical support staff, the ease of control and training, the ability to operate at long range, the improved clarity of the communication and phone system, the provision of the family override, the new door opening feature and the comprehensive control of entertainment systems.
