Abstract :
Because of the non-linearity, time-delay existing in alkaline pefoxide mechanical pulp (APMP) wastewater treatment process, a fuzzy expert control strategy based on DCS was proposed in this paper. A feedforward and feedback plus PID control scheme based on expert system (ES) for dissolved oxygen (DO) value control was designed, by which different control rules were made according to the derivative of DO values in different stages. Based on SIMATIC PCS7, the control system was designed for the aerobic section of APMP wastewater treatment. The application indicates that the proposed control method is feasible and valuable.
