Abstract: Combined fuzzy logic with chaos neural-network, a new fuzzy chaos neural-network adaptive control scheme is proposed for unknown-model spatio-temp oral chaos in coupled system by utilizing the approximation capacity of the fuzzy logic and the spatio-temporal behavior of the chaos neural-network. Taken t he effects from disturbance, unmodeled dynamics and modeling errors into account , the additional adaptive compensation controller is designed to improve the rob ustness of the spatio-temporal chaos control scheme. The stability of the proposed method is verified with Lyapunov method, and the effectiveness and the robus tness of the scheme are demonstrated via simulation examples.
Keyword: spatio-temporal chaos , chaos neural-network, adaptive control robust ness.
