N2 - This paper presents a novel real-time control approach for a class of nonlinear unknown systems. The system is assumed to be represented by an affine model where all the involved nonlinear functions are on-line estimated by fuzzy logic units. Using these on-line estimations, an adaptive nonlinear control algorithm is established which consists two loops, the inner loop and outer loop. The inner loop is used to compensate the unknown nonlinea-rities whilst the outer loop is utilised to eliminate the DC component in the tracking error for the closed loop system. A real application to a pH control process in paper making has been made and desired results have been obtained.
