Considering the characteristics of the time-delay, inertia and time-varying of DO control in the wastewater treatment, and on the basis of analyzing the defects on general PID control and Fuzzy Smith-PID control, one kind of ADRC controller is proposed in the wastewater treatment control system, Through the simulation experiment and comparing with general PID and Fuzzy Smith-PID control, the result...
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...
