| Abstract: | Based on fuzzy logic system with the properties of fully utilizing linguistic information and approximating any nonlinear continuous function, the decentralized adaptive robust control laws of nonlinear complex systems with uncertainties was discussed. By using the model of the complex systems and output information coming from the fuzzy logic system about uncertain factors, the decentralized adaptive robust controller and adaptive laws of parameter estimate of fuzzy logic system were constructed. Under some simple conditions, the laws and controller made the states of systems controlled and parameter estimate errors uniformly ultimately bounded (UUB). Finally, the computer simulation showed the validity of the approach. |
