Multi-model approaches for Integrated Design of Wastewater Treatment Plants with Model Predictive Control

摘要

In this work some multi-model and norm based approaches for Integrated Design of processes and constrained Model Predictive Control systems have been proposed. The Integrated Design procedure provides simultaneously the plant dimensions and working point together with the parameters of the control system by solving a multi-objective constrained non-linear optimization problem. Particularly, the cost functions include investment, operating costs, and dynamical indexes based on the weighted sum of the H_∞ and l_1 norms of different closed loop transfer functions matrices of the system, following a novel robust approach. The paper illustrates the application of the proposed methodology for the Integrated Design of the activated sludge process of a wastewater treatment plant (WWTP).
