Abstract :
Based on fuzzy logic system with the properties of fully utilizing linguistic information from experts and approximating any nonlinear continuous function with arbitrary, a class of nonlinear complex system with uncertainties is considered, the decentralized adaptive output feedback robust controller and adaptive laws of parameter estimate for fuzzy logic system are presented. Under some simple conditions, the laws and controller make the states of systems controlled and parameter estimate errors uniformly ultimately bounded (UUB). Finally, the computer simulation shows the method validity.
