13. Study of a cooling system with air forced with monitoring of electrical energy consumption / Estudo de um sistema de resfriamento com ar forçado com monitoramento do consumo de energia eletrica
This work is a study of a classical controller implementation using tuning method referred to as IMC (Internal Model Control), aimed at reducing electrical energy consumption that proceed the appropriate relation between this consumption and cooling time of the cooling process with forced air. For this, the supervisory system installed is able to manipulate

16. Controle preditivo baseado em rede de modelos lineares locais aplicado a um reator de neutralização / Predictive control based on local linear model networks applied to neutralization reactor
Uma malha de controle com baixo desempenho implica em um aumento dos custos de produção, causando descarte de produto fora da especificação e desgaste desnecessário dos elementos finais de controle. A depender do processo controlado, uma malha deficiente pode também acarretar em paradas não previstas na planta e até mesmo em danos ao meio ambiente. D

17. Sistema de irrigação por capilaridade na produção de porta-enxertos de mudas citricas na fase de sementeira / Irrigation system by capillary action in the citrus rootstocks production in seedings stage
The water and nutrition management in the production of citrus rootstocks in the seedling phase performed by sprinkler systems, manually operated, presents the environmental outcome of water or residual solution disposal from the fertigation. The generated wastewater is generally discarded directly in the soil with the risk to reach the groundwater and conta

18. Ambiente para desenvolvimento de aplicações fuzzy industriais / Ambiente para desenvolvimento de aplicações fuzzy industriais
This paper describes the design, implementation and enforcement of a system for industrial process control based on fuzzy logic and developed using Java, with support for industrial communication protocol through the OPC (Ole for Process Control). Besides the java framework, the software is completely independent from other platforms. It provides friendly an

19. Simulação e controle do processo de produção de levedura
The yeast Saccharomyces cerevisiae can be useful in several ways in bioprocesses. It is widely used in anaerobic processes for production of bioethanol at Brazilians plants. It is also of great importance as bakers yeast, where the product is the biomass. Moved by the industrial interest this work will aggregate knowledge in the improvement of techniques of

20. Reconfiguração dinâmica de estratégias distribuídas em dispositivos foundation fieldbus para a otimização de processos na indústria do petróleo
The petrochemical industry has as objective obtain, from crude oil, some products with a higher commercial value and a bigger industrial utility for energy purposes. These industrial processes are complex, commonly operating with large production volume and in restricted operation conditions. The operation control in optimized and stable conditions is import

21. IEC-61850: interoperability and interchangeability between supervision, control and protection equipment using data communication networks / IEC-61850: interoperabilidade e intercambialidade entre equipamentos de supervisão, controle e proteção através das redes de comunicação de dados
Data communication has always been considered as a critical factor in real time operation of electric power systems. This is due to the need for fast and accurate decisions at different locations, from power generation to the user interfaces. With the digital technology, measurement, signals and commands are encrypted into data packets that travels on the su

22. Uma arquitetura baseada em agentes para configuração dinâmica de aplicações inteligentes em ambiente foundation fieldbus
The industrial automation is directly linked to the development of information tecnology. Better hardware solutions, as well as improvements in software development methodologies make possible the rapid growth of the productive process control. In this thesis, we propose an architecture that will allow the joining of two technologies in hardware (industrial

23. Uma proposta para o controle automático da repartida de poços operando por gas lift contínuo
The gas-lift wells restart process has high complexity. If the procedure is not carefully executed, the production liquid flowrate can show an oscillatory behaviour, called #severe slugs#. This situation is undesirable because it causes productivity loss, decreases oil-watergas separation process performance or can lead to the shutdown of the system. Nowaday
