Abstract

A conditional fuzzy c-means (CFCM)-based fuzzy adaptive neuro-fuzzy system (ANFS) by on-line learning is proposed in this paper. In the structure identification, the optimal or near optimal number of fuzzy rules is determined by a CFCM clustering with TSK-type fuzzy rules based on the criterion. In the parameter identification. The consequent parameters are tuned by least squares estimator (LSE) and the premise parameters are tuned by back-propagation algorithm in off-line learning. Then on-line learning by recursive least squares estimator (RLSE) and back-propagation algorithm is used to cope with time varying plant dynamics. Finally, we show its capability for a CFCM-based on-line ANFS to control the temperature of a water path.
