摘要：In order to reduce energy consumption of aeration processes, an optimal control was studied. Simplified model of aeration system was built according to Activated Sludge Model No.1 (ASM1) presented by International Association on Water Quality (IAWQ), then the optimal control strategy based on reduced-order observer was brought forward for the aeration system. The proposed optimal control strategy was implemented on a benchmark wastewater treatment process-Benchmark Simulation Model 1(BSM1). Compared with PID control strategy recommended in benchmark, using the proposed control strategy, the effluent water quality and the time of effluent water quality exceeding the discharge standard of BSM1 are more stable, while more than 4% aeration energy is saved. ? 2012 IEEE.
