Abstract

© 2017 Elsevier B.V. This paper addresses the implementation of economic oriented model predictive controllers for the dynamic real time optimization of the operation of wastewater treatment plants (WWTP). The controller cost function includes the energy consumption and the fines for effluent ammonia violations as economic performance indices. The economic optimizing controller and the economic oriented tracking controller formulation are considered to be used directly for control in the BSM1 platform. The different designs and structures is compared in terms of satisfactory plant behaviour and operating costs. A non-linear reduced model of the process is used for predictions to get a reasonable computing effort. Their use as a unique model for optimization and control in the single-layer structures prove to be an advantage respect to the two-layer implementation.
