An adaptive fuzzy control scheme is presented to control model unknown coupled spatio-temporal chaos composed of high-dimensional continuous-time subsystems. This method integrates the merits of approximate ability of adaptive fuzzy system and robustness of the sliding control. By using Lyapunov method we have proved the stability of the scheme. The effectiveness and the feasibility of the proposed method are demonstrated through simulations on the continuous time coupled Duffing oscillator spatio-temoral chaos.
