On fuzzy logic controllers
Biao Zhang, John M. Edmunds · Control 1991. Control '91., International Conference on · 1991
The authors present analytical models of a kind of fuzzy logic controllers, by which the fuzzy control system can be analysed using nonlinear control systems theory. The fuzzy control rules and the membership functions of fuzzy labels representing linguistic concepts and the normalisation factors are linked to the structure and the parameters of a nonlinear nonfuzzy controller. In this way some methods used in nonlinear control systems analysis can be adapted to help in the design and analysis of fuzzy logic controllers.
