Abstract :
The authors discuss the stability of a fuzzy control system by applying conventional stability analysis methods. A nonlinear fuzzy controller is characterized by using a sector condition and the resultant system is transformed into a Lure system. A condition of absolute stability is derived for the system and the tracking property is checked for uncertain cases through simulation, by applying conventional stability criteria. Both continuous and discrete systems are considered
