Multifractal detrended fluctuation analysis of sheep livestock prices in origin
(Elsevier, 2013)The multifractal detrended fluctuation analysis (MF-DFA) is used to verify whether or not the returns of time series of prices paid to farmers in original markets can be described by the multifractal approach. By way of ... -

A practical tuning methodology for event-based PI control
(Elsevier, 2014)This paper is focused on the tuning of an event-based PI controller for first-order plus time delay systems(FOPTD). In this work, a novel design and combination of a controller and event generator with an easy-to-use tuning ... -
Design of event-based PI-P controllers using interactive tools
(Elsevier, 2014)In the field of event-based control, the tuning and synthesis of controllers represents a challenging task where the lack of specific computer-aided design tools makes very difficult the consolidation of emerging approaches. ... -
Control of a PEM fuel cell based on maximum power tracking using radial basis function neural networks
(European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ), 2014)This article presents the proposal of a two-level control approach for a type of commercial PEM fuel cell. Thus, in the external control level a model based on neural networks of the FC is used together with a tracking ... -
Comparative analysis of decoupling control methodologies and H∞ multivariable robust control for VS-VP wind turbines
(IEEE, 2015)Wind turbines systems considered multivariable processes can work in several operational modes. Each mode can be represented with a dynamic model. This fact supposes a difficulty in controlling these types of systems. In ... -
Modeling and optimization of acetic acid fermentation: A polynomial-based approach
(Elsevier, 2015)Vinegar production is a typical bioprocess in the scope of the agrifood industry. Its optimization requirescareful modeling which has so far been addressed by using mainly unstructured first principles models. Because of ... -
Preparation of a pure inoculum of acetic acid bacteria for the selective conversion of glucose in strawberry purée into gluconic acid
(Elsevier, 2015)Strawberry surpluses, which may account for about 20% of the whole production, could bean example of what is happening with other fruits. This surplus is largely transformed intostrawberry purée which, although is especially ... -
Interactivity-based control education: Some experiences at the University of Córdoba
(Elsevier, 2015)In this work, it is described some of the experiences of the Department of Computer Science and Numerical Analysis of the University of Cordoba about the use of interactive tools in courses on process control. This experience ... -
Characterization and tuning of predictive SSOD-PI controllers
(IEEE, 2015)This work proposes an event-based PI control scheme focused on FOPTD (First Order Plus Time Delay) processes with simple tuning methods. The scheme, called for short predictive SSOD-PI or PSSOD (Predictive Symmetric Send ... -
Event-based control for IPTD processes with simple tuning methods
(IEEE, 2015)The event-based control of Integrator Plus Time Delay (IPTD) processes is investigated in this study. A two Degree-Of-Freedom (2-DOF) structure with simple tuning methods is proposed to cope with the set-point tracking ... -
Multivariable PID control by decoupling
(2016)This paper presents a new methodology to design multivariable PID controllers based on decoupling control. The method is presented for general n×n processes. In the design procedure, an ideal decoupling control with integral ... -
Smith Predictor with Inverted Decoupling for Square Multivariable Time Delay Systems
(2016)This paper presents a new methodology to design multivariable Smith predictor for n×n processes with multiple time delays based on the centralized inverted decoupling structure. The controller elements are calculated in ... -
An approach for estimating the maximum specific growth rate of Gluconobacter japonicus in strawberry purée without cell concentration data
(Elsevier, 2016)The estimation of the maximum specific growth rate ( max) for non-readily culturable bacteria, growing on complex media containing suspended solids, is a difficult task considering the important problems in obtaining ... -
Gluconic acid: Properties, production methods and applications—An excellent opportunity for agro-industrial by-products and waste bio-valorization
(Elsevier, 2016)Agro-industrial by-products and wastes pose serious, widespread problems with considerable economic and environmental consequences in developed countries. However, many of the by-products contain large amounts of sugars ... -
Revalorization of strawberry surpluses by bio-transforming its glucose content into gluconic acid
(Elsevier, 2016)Modern societies produce massive surpluses of food, by-products and wastes that increase the interest for their revalorization. This work examines the use of a culture of Gluconobac-ter japonicus CECT 8443, without pH ... -
