1. Implementation of supervisory control in PLCs using high-level language / Implementação de controle supervisório em CLPs usando linguagem de alto nível
Hoje em dia a competitividade entre as empresas está cada vez maior. Em um sistema de produção, a eficácia, a velocidade e a flexibilidade são importantes, pois significam redução de custos. Os sistemas de automação atuais estão cada vez mais complexos, justificando a necessidade de programas de controle mais eficientes, sem erros e de fácil manut

2. Automation in water supply systems. Case of the reservation control distribution / Automação nos sistemas de abastecimento de água. Caso do controle da reservação de distribuição
Industrial automation systems applied in water supply were quite simple until recently. The advent of Programmable Controllers, associated with the development of modern control theory, allowed a greater and more effective automation of these systems. This paper discusses the use of automation in sanitation systems implementing "artificial intelligence" for

3. Metodologia para implementação de controle supervisório modular local em controladores lógicos programáveis / Methodology for implementation of supervisory control local modular in programmable logic control
Currently, manufacturing automation has assumed an increasingly important role within the industry and the problems of automated control systems have become increasingly complex. Thus, the traditional use of empirical methods heavily base on the experience of the programmer can lead to inappropriate or ineffective solutions. In this case, the Supervisory Con

4. Controle supervisÃrio da cadeia produtiva do biodiesel da mamona baseado em redes de Petri / Supervisory control of castor bean biodiesel suppy chain based on Petri nets
Nowadays many countries present critical problems related to energy demand-supply equilibrium. The reserves of petroleum-based products are unable to face future demand for the next decades. So, the search for alternative sources of energy has been strongly directed to biodiesel. Several fruit oils can be used as a source for biodiesel production and the cas

5. O uso da simulação no suporte a implementação da estrutura de controle supervisório
Abstract: The growth of competitiveness in enterprises has forced them to reduce more the releasing time of their products. Consequently, the enterprise and academy s effort in providing techniques and tools for the reconfiguration of its systems is in force. A manufacturing system is a classical example of a Discrete-Event System (DES), for its dynamics dev

6. Uma abordagem híbrida para o controle de sistemas de manufatura baseada na teoria de controle supervisorio e nas redes de Petri coloridas
Abstract: This paper presents a hybrid control approach for flexible manufacturing systems. The architecture is based on two formalisms: Supervisory Control Theory and Colored Petri Nets. Supervisory Control Theory and one of its extensions, the local modular approach, are used for treating safety and sequence related requirements. Colored Petri Nets are use

7. Application of Fuzzy Logic in the Production of Penicillin G Acylase in Bacillus megaterium Cultivations. / Aplicação da lógica fuzzi na produção de penicilina G Acilase em cultivos de Bacillus megaterium.
Penicillin G acylase (PGA) is an important enzyme for the pharmaceutical industry. This enzyme has industrial use in the hydrolysis of penicillin G to obtain 6-aminocephalosporanic acid (6-APA), essential intermediate for the production of beta-lactam antibiotics. Many microorganisms produce PGA, but Bacillus megaterium is one of the few that excretes the en

8. PROCESS CONTROL SYSTEMS : DEPENDABILITY AND PERFORMANCE MODELING
Today, a wide variety of computer systems are required to react automatically to various events generated by external processes and/or human operators. An important class of these process control systems, called hard real-time systems, need to respond to events under severe timing constraints expressed in terms of deadlines and earliest starting times. In ge
