【Abstract】 Combined fuzzy logic with chaos neural-network,a new fuzzy chaos neural-network adaptive control scheme is proposed for unknown-model spatio-temporal chaos in coupled system by utilizing the approximation capacity of the fuzzy logic and the spatio-temporal behavior of the chaos neural-network.Taken the effects from disturbance,unmodeled dynamics and modeling errors into account,the additional adaptive compensation controller is designed to improve the robustness of the spatio-temporal chaos control scheme.The stability of the proposed method is verified with Lyapunov method,and the effectiveness and the robustness of the scheme are demonstrated via simulation examples.更多还原
