Fuzzy Universal Model Approximator for Distributed Solar Collector Field Control

摘要

This paper deals with the control of concentratingudparabolic solar collectors by forcing the outlet oil temperatureudto track a set reference. A fuzzy universal approximate modeludis introduced in order to accurately reproduce the behaviorudof the system dynamics. The proposed model is a low orderudstate space representation derived from the partial differentialudequation describing the oil temperature evolution using fuzzyudtransform theory. The resulting set of ordinary differentialudequations simplifies the system analysis and the control law designudand is suitable for real time control implementation. Simulationudresults show good performance of the proposed model.
