Abstract :
According to the characteristics of long time-delays, large inertia and time-variation in the dissolved oxygen control method of sewage treatment, one fuzzy-Smith control model on dissolved oxygen control is presented in this paper. This model has the merits of a high robustness in fuzzy controller and a compensation for time delay in Smith predictor. After simulation experiment, the result is shown that this control model has both good robustness and stability when it matches the model or not, which is provided an effective approach to solve time-variation system of long time-delays and large inertia.
