Fuzzy Inference in Rule-Based Real-Time Control

Abstract

In this paper research into the application of 'expert system'-like inference mechanisms in the field of fuzzy control is adressed. Using techniques from the area of rule-based expert systems, a more flexible way of design and modification is presented of new and existing fuzzy systems for modelling and control. In comparison with 'normal' applications of fuzzy inference, the 'compositional rule of inference' is replaced by a fuzzy inference engine. General applicability of the fuzzy inference engine is made possible by its general character as a fuzzy expert system shell. Succesful implementations in simulation and realtime control environments show the flexibility and usefullness of the described fuzzy inference engine.
