Extension of modifier adaptation for controlled plants using static open-loop models
(Pergamon-Elsevier Science Ltd, 2016-10)
Model-based optimization methods suffer from the limited accuracy of the available process models. Because of plant-model mismatch, model-based optimal inputs may be suboptimal or, worse, unfeasible for the plant. Modifier ...
Modifier Adaptation for Real-Time Optimization - Methods and Applications
(MDPI, 2016-12)
This paper presents an overview of the recent developments of modifier-adaptation schemes for real-time optimization of uncertain processes. These schemes have the ability to reach plant optimality upon convergence despite ...
Modifier Adaptation as a Feedback Control Scheme
(American Chemical Society, 2020-02)
As a real-time optimization technique, modifier adaptation (MA) has gained much significance in recent years. This is mainly due to the fact that MA can deal explicitly with structural plant-model mismatch and unknown ...
Will climate change cause spatial mismatch between plants and their pollinators? A test using Andean cactus species
(Elsevier, 2018-10)
Climate change can disrupt mutualisms by causing temporal or spatial mismatch between interacting species. However, the effects of climate change forecasts on biotic interactions remain poorly studied. In cactus species, ...
A note on efficient computation of privileged directions in modifier adaptation
(Pergamon-Elsevier Science Ltd, 2020-01)
In the presence of plant-model mismatch, the estimation of plant gradients is key to the performance of measurement-based iterative optimization schemes. However, gradient estimation requires time-consuming experiments, ...
Detecção de erros planta-modelo em sistemas de controle preditivo (MPC) utilizando técnicas de informação mútuaDetecting plant-model mismatch in predictive control systems (MPC) using mutual information techniques

Active directional modifier adaptation for real-time optimization
(Pergamon-Elsevier Science Ltd, 2018-07)
Modifier adaptation is a real-time optimization (RTO) methodology that uses plant gradient estimates to correct model gradients, thereby driving the plant to optimality. However, obtaining accurate gradient estimates ...
Climate niche mismatch and the collapse of primate seed dispersal services in the Amazon
(2020-07-01)
Animal-plant interactions are threatened by ongoing climate change, deforestation, and defaunation. The disruption of biotic interactions leads to loss of ecosystem services but estimates of the magnitude of reductions are ...
Conservation priorities in the Southern Central Andes: mismatch between endemism and diversity hotspots in the regional flora
(Springer, 2014-01)
North western Argentina, the southernmost portion of the tropical Andes, contains one of the main areas of endemism within the Southern Cone, as well as one of the main diversity hotspots of the country. Historically its ...
Modifier adaptation with guaranteed feasibility in the presence of gradient uncertainty
(Pergamon-Elsevier Science Ltd, 2017-01)
In the context of real-time optimization, modifier-adaptation schemes use estimates of the plant gradients to achieve plant optimality despite plant-model mismatch. Plant feasibility is guaranteed upon convergence, but not ...
