User-friendly method for tuning fuzzy logic controllers
Hakan B. Gürocak · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1998
Design of a fuzzy logic controller (FLC) is generally based on trail-and-error because no standard method exists for developing the rule base of an FLC directly from human knowledge. Consequently, the performance of an initial design attempt will, in general, not be satisfactory in terms of certain design criteria such as steady state error and/or oscillatory behavior of the system. In this paper, a method to tune the rule base of such an initial design attempt is presented. The method is based on a novel formulation of an objective function which can then be used in a conventional optimization algorithm. Results of two experiments are reported.
