Inspired by biologic nature of flying wild geese, a so-called process goose queue (PGQ) technique oriented for plant-wide optimization is established. Taking advantage of this ad-hoc structure of flying geese, a plant-wide process can be decomposed into several hierarchically connected PGQs along the direction of the objective function generation. In line with this thought, plant-wide process o...

For plant-wide control, many single loop controllers are utilized. Although tuning of a control loop is focused in control theory, control loop configuration problem is more essential problem. If control loop configuration is not adequate, controller cannot be stabilized with any tuning of controller parameters. Moreover, controller can be unstable by mode change of some other controllers. Thes...

This paper describes a simple and reliable method to acquire information instantaneously on the basis of predictive computations of data acquired with significant time delay. The estimated value of any measured variable is the output of a virtual sensor implemented by means of a virtual engineering programming tool. Copyright © 2000 IFAC

In this work a new systematic and generalized strategy to solve the MIMO plantwide control problem is proposed. The methodology called Minimum Square Deviation (MSD) considers several points such as the optimal sensor location (OSL) based on the sum of square deviation (SSD) and the control structure selection (CSS) based on net load evaluation (NLE) problems simultaneously. Particularly, this ...

This work explores the possibilities of improving eco-efficiency Wastewater Treatment Plants (WWTPs) introducing a plant-wide perspective in formulation control strategy. Eco-efficiency goals are contemplated analysis appropriateness actions, considering seasonal effects temperature into decision-making process. Plant-wide strategy handles operation variables activated sludge process, volume pr...
