| Abstract | In this paper, a complete design framework for a fuzzy constraint-based controller based on fuzzy constraint processing and its semantics and relationship to fuzzy logic is presented. The concept of "fuzzy constraints" in a problem solving is introduced and some basic definitions of fuzzy constraint processing in a constraint network and its semantic modeling are addressed. Then a fuzzy local propagation inference mechanism for reasoning about imprecise information applying the filter operation in a network of constraints is proposed. Moreover, we advance the concurrent fuzzy logic controller (FLC) to a new type of controller, the fuzzy constraintbased controller (FCC), using a more general predicate calculus and full first-order logic knowledge representation and making use of the idea of fuzzy constraint processing to model practical dynamic control systems. Finally, simulation results show that a FCC achieves equivalent performance as PD type and PI type FLCs and also demonstrates s... |
