A critical characteristic of most WECs (wave energy converters) is the large peak-to-average power ratio. This poses many challenges to design high-efficient PTO (power take-off) systems and, even more importantly, integrate this form renewable into grids. The OWC (oscillating water column) are devices whose uses an air turbine as primary converter. Besides its inherent simplicity, probably greatest advantage based ability control or dissipate any excess available system that may occur in...

A major issue in drug delivery systems is the high level of uncertainty due to inter- and intrapatient variations dynamics absorption metabolism. This paper proposes an approach tackle this problem based on supervised multimodel adaptive control (SMMAC). Although specific case neuromuscular-blockade-level patients subject general anesthesia considered, overall procedure can be applied other physiological variables. Design guidelines implement SMMAC are presented, together with clinical cases...

This paper deals with temperature control in an industrial-scale distributed collector solar field. The need for adaptive arises from the highly time-varying behaviour of both plant dynamics and radiation effects field due to atmospheric changes. problem consists keeping constant outlet oil by acting on flow. manipulated variable is chosen so as minimize a receding horizon quadratic cost. underlying law model-based predictive type, adaptively implemented MUSMAR algorithm, modified exploit...

Distributed collector solar fields are spatially distributed engineering systems, which aim at collecting and storing energy from radiation. They formed by mirrors concentrate direct incident sun light in a pipe where fluid, able to accumulate thermic energy, flows. From the control point of view, objective considered here consists making outlet oil temperature track reference signal manipulating flow, possible presence fast disturbances caused passing clouds. Although this plant may be...

SUMMARY This survey paper aims, to present in a systematic way, the ‘state‐of‐the‐art’ of class so called optimized adaptive control methodologies, where systems theory is complemented by optimal theory. It based on literature published since 1958 and emphasizes results with proven industrial relevance. After recalling previous systems, that had prepared ground for new ideas, analysis departs from work predictive mid 1970s, which provided conceptual basis development this kind technique....

Purpose: Our study aims to 1) characterize and analyze food intake typical external load in young soccer players over a normal microcycle; 2) correlate energy macronutrient with training parameters. Methods: Eighteen high-level junior male (17.61 ± 0.49 years old) had their nutritional assessed during mid-season competitive week November 2022, which included two matches structured schedule. Anthropometric measurements, following ISAK methodology, were taken by certified technician. Dietary...

This paper describes an algorithm for tracking groups of objects in video sequences. The main difficulties addressed this work concern total occlusions the to be tracked as well group merging and splitting. A two layer solution is proposed overcome these difficulties. first produces a set spatio temporal strokes based on low level operations which manage track active regions most time. second performs consistent labeling detected segments using statistical model Bayesian networks. network...

The problem addressed in this article consists of the motion control a quadrotor affected by model disturbances and uncertainties. In order to tackle uncertainty, adaptive based on reinforcement learning is used. distinctive feature article, comparison with other works using learning, exploration underlying optimal which quadratic cost linear dynamics allow for an algorithm that runs real time. Instead identifying plant model, adaptation obtained approximating performance index given...

O Acidente Vascular Cerebral (AVC) é uma das principais causas de morbidade e mortalidade entre a população idosa. objetivo deste estudo foi analisar fatores risco estratégias prevenção do AVC em idosos, com foco no controle hipertensão, uso medicamentos, mudanças estilo vida adesão ao tratamento. Para isso, realizada revisão integrativa da literatura, análise artigos publicados nos últimos cinco anos. As bases dados utilizadas foram PubMed Biblioteca Virtual Saúde (BVS), os critérios...

Generalized-predictive-control- (GPC-) type laws are developed in order to obtain a guaranteed stable closed-loop system. The design methodology consists of an input/output receding-horizon control strategy based on the minimization multistep quadratic cost under constraint that terminal state vanish. resulting law, denominated SIORHC, provides stabilizing feedback gains for finite-horizon criteria. A special case which GPC and SIORHC coincide, hence is proved yield stability, also...

Abstract Penicillin‐G fermentation with industrial media in 1 m 3 stirred tank bioreactors was studied. A model based on the Bajpai–Reuss structure developed. Under typical production conditions catabolite repression is nonidentifiable and extensive mycelium differentiation occurs. Thus, original reformulated, neglecting glucose of penicillin including biomass autolysis. The multi‐substrate nature critically analysed. By combining two most important carbon substrates present, a simple...

Networks are prevalent in many human activities such as communication, transport, energy, and water delivery drainage. Large networks that spread over wide-space areas cross the borders of different administrative regions, or even countries, managed by regional decision centers may have to comply with legal requirements. With networking comes complexity need coordinate local decisions, which is an issue for control optimization can provide significant contributions. The sources many,...
