- A programmable controller suited for automation applications of highest safety criticality is presented. Its features are input conditioning by low-resolution analogue-to-digital converters, inference by look-up in rule set tables, strictly periodic and jitter-free operation, high speed and simplicity of design. A fail-safe supervisor immediately initiates an emergency shut-down in case of a malfunction. The software in form of rule base tables can easily be verified by inspection. This device is used to implement control algorithms working with set-point preprocessors, which calculate internal set-point graphs of controlled variables in such a way that very high controller gains are attainable and, thus, stability is increased. The performance of these „SPP” controllers is closer to the „best physically possible”, and much more predictable than the one of conventional control structures. The otherwise conficting design objectives stability, safety, high speed, small energy consumption, or steady and harmonic temporal controller output values can nearly all be achieved.
