Applying variable dissolved oxygen set point in a two level hierarchical control structure to a wastewater treatment process
TL;DR: In this paper, a two-level hierarchical control structure for biological wastewater treatment plants, with the goal of improving effluent quality and reducing operational costs, is presented, which allows to adjust the dissolved oxygen in the fifth tank (S O,5 ) according with the working conditions, instead of keeping it in a fixed value.
Journal ArticleDOI
PID control in terms of robustness/performance and servo/regulator trade-offs: A unifying approach to balanced autotuning
TL;DR: In this paper, the authors address the model-based tuning of single-loop PID controllers in terms of the robustness/performance and servo/regulator trade-offs.
Journal ArticleDOI
Advanced decision control system for effluent violations removal in wastewater treatment plants
TL;DR: In this paper, the authors present the application of control strategies for wastewater treatment plants with the goal of effluent limits violations removal as well as achieving a simultaneous improvement in effluent quality and reduction of operational costs.
Journal ArticleDOI
Fuzzy Control and Model Predictive Control Configurations for Effluent Violations Removal in Wastewater Treatment Plants
TL;DR: In this article, a hierarchical control structure is implemented to regulate the dissolved oxygen (DO) on the three aerated tanks, with a fuzzy controller that adapts the DO set points of the low level based on the NH concentration in the fifth tank (NH5), and low level is composed of three MPC controllers with feedforward control (MPC + FF).
Journal ArticleDOI
Control strategies for nitrous oxide emissions reduction on wastewater treatment plants operation
TL;DR: The results show that the proposed control strategies are able to reduce by 29.86% of nitrous oxide emissions compared to the default control strategy, while maintaining a satisfactory trade-off between water quality and costs.
