Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Computer control is entering all facets of life from home electronics to production of different products and material. Many of the computers are embedded and thus ``hidden'' for the user. In many situations it is not necessary to know anything about computer control or real-time systems to implement a simple controller. There are, however, many situations where the result will be much better when the sampled-data aspects of the system are taken into consideration when the controller is designed. Also, it is very important that the real-time aspects are regarded. The real-time system influences the timing in the computer and can thus minimize latency and delays in the feedback controller. The paper introduces different aspects of computer-controlled systems from simple approximation of continuous time controllers to design aspects of optimal sampled-data controllers. We also point out some of the pitfalls of computer control and discusses the practical aspects as well as the implementation issues of computer control. Published as a Professional Briefs by IFAC.

Tidskriftsartikel (refereegranskat)abstract
- There has been substantial progress in the theory and practice of automatic control through application of mathematical analysis and numerics. Symbolic data processing has, however, so far only had marginal influence on control systems despite the fact that the actual engineering of control systems contains a substantial amount of heuristic logic. This paper shows how the logic may be replaced by an expert system. This leads to simplification of conventional systems and makes it possible to obtain control systems with new capabilities.
