Abstract :
A multi-layer neuro-fuzzy system presents identification of a drum type boiler. This identification provides a rule-based approach to approximate the boiler dynamics. The interconnections of neuro-fuzzy layers furnish these fuzzy rules. A genetic algorithm (GA) trains the neuro-fuzzy identifier and extracts the linguistic fuzzy rules from measured boiler data. This GA training takes the advantages of nonbinary alphabet and compound chromosomes to train the neuro-fuzzy identifier. An error backpropagation training methodology is chosen to tune the membership function parameters. This neuro-fuzzy identifier obtains time response similar to boiler model while it avoids mathematical complexity of model dynamics
