On Handling Cost Gradient Uncertainty in Real-Time Optimization

Dominique Bonvin, Timm Faulwasser, Martand Singhal

This paper deals with the real-time optimization of uncertain plants and proposes an approach based on surrogate models to reach the plant optimum when the plant cost gradient is imperfectly known. It is shown that, for processes with only box constraints, ...

Applications of Nanoparticles for Reactive Oxygen Species (ROS) Scavenging in Photosynthetic Systems

Ardemis Anoush Boghossian

Under aerobic conditions, excessive illumination results in the photogeneration of reactive oxygen species (ROS) responsible for protein damage and photo-inhibition during photosynthesis. We explore the effects of nanoceria (NC), a regenerative ROS scaveng ...

On the Use of Transient Information for Static Real-Time Optimization

Dominique Bonvin, Grégory François, Alejandro Gabriel Marchetti

Optimal operation of chemical processes is key for meeting productivity, quality, safety and environmental objectives. Both model-based and data-driven schemes are used to compute optimal operating conditions [1]: - The model-based techniques are intu ...

Real-Time Optimization via Directional Modifier Adaptation, with Application to Kite Control

Sean Costello

The steady advance of computational methods makes model-based optimization an increasingly attractive method for process improvement. Unfortunately, the available models are often inaccurate. The traditional remedy is to update the model parameters, but th ...

Effects of hydropeaking waves offsets on growth performances of juvenile Salix species

Alexandre Buttler, Paolo Perona, Pascal Turberg, Constant Signarbieux, Lorenzo Gorla

Hydropower production and other human activities change the natural flow regime of rivers (e.g., hydropeaking effects), in turn, impacting the riparian environment. Here we present an experiment conceived to investigate the response of forced offsets in wa ...

Microclimatological consequences for plant and microbial composition in Sphagnum-dominated peatlands

Luca Bragazza, Bjorn Jozef Maria Robroek

In three Scandinavian peatlands we studied to what extent plant and microbial community compositions are governed by local-scale microhabitat, with a special interest in the effect of aspect (i.e. exposition of slopes). Despite differences in solar irradia ...

On the Use of Second-Order Modifiers for Real-Time Optimization

Dominique Bonvin, Timm Faulwasser

We consider the real-time optimization of static plants and propose a generalized version of the modifier-adaptation strategy that relies on second-order adaptation of the cost and constraint functions. We show that second-order adaptation allows checking ...

Use of Transient Measurements for the Optimization of Steady-State Performance via Modifier Adaptation

Dominique Bonvin, Grégory François

Real-time optimization (RTO) methods use measurements to offset the effect of uncertainty and drive the plant to optimality. RTO schemes differ in the way measurements are incorporated in the optimization framework. Explicit RTO schemes solve a static opti ...
