Fuzzy supervisory control and substrate addition to improve effluent quality in an activated sludge wastewater treatment plant

摘要

In this paper, we explore the combination of two control strategies for activated sludge wastewater treatment plants. From the plant configuration proposed by the Benchmark of the European group COST 624, first a fuzzy supervisory control which adequate the parameters of two local controllers is described and applied, then it is combined with a control strategy previously developed: extra substrate addition. Finally, different control strategies are compared via simulations.
