Intelligent Control Structure for Control of Integrated Wastewater Systems

Abstract The paper proposes an approach to design a structure for control of integrated wastewater treatment plant-sewer system under full range of disturbance inputs. The control activities are hierarchically structured into a multilevel-multilayer form. A newly developed robust Model Predictive Control method for uncertain and output constrained dynamic systems is a key control technology employed at Optimising Control Level. This level is further decomposed into control layers operating at different time scales: slow, medium and fast. Appropriate models for control purposes is described Needed data are delivered by measuring system and Extended Kaiman Filter. A Supervisory Control Level is located at a top of the control hierarchy.
