Interpolate Fuzzy Reasoning Based Fault Classification and System Reconfiguration

摘要

In case of redundant systems some kind of faults could be tolerated simply by changing the rulebase of the control system - by a system (strategy) reconfiguration. One solution for this kind of system reconfiguration could be the combination ofthe fuzzy clustering and interpolate fuzzy reasoning based symptom evaluation and the hierarchical interpolate fuzzy reasoning - the similarity based system reconfiguration. Its main idea is the following: More similar the actual symptom to one of thesystem behaviour classes, more similar must be the conclusion to the decision done by the strategy belonging to that system behaviour. A similarity based system reconfiguration method and as an example of its practical application, fault diagnosis andreconfiguration of a simplified three-tank benchmark system will be introduced in this paper.
