| Aim: The use of computers in control systems gives rise to special problems of a technical nature. These are a consequence of the fact that all signals, both those that are measured and those that are calculated, can only be known with a certain degree of accuracy. It is the aim of the course to give the participants some knowledge of these problems and to teach them some rational methods for designing control algorithms, in order that the effect of limited accuracy can be reduced as much as possible. Furthermore, the course looks at the problems surrounding the interaction between the internal structure of the computer and the basic software, on the background of the special control requirements that have to be met by the computer system as a whole. |
| Contents: General overview of the possible applications of computers to control technology. Programming controller algorithms. Error sources in controller algorithms, including calculations time delay, amplitude quantization and product quantization. Methods for analysing the significance of quantization errors for control quality. Computerised systems for process control are reviewed, including the structure of the computer, external I / O units and the structure of operating systems for process control. |
| Remarks: The practical part of the course consists of 4 small excercises that introduce the computer system to the students and a large excercise that illustrates the problems arising when using computers for control and automation. |
