1. Desenvolvimento de um controlador de irrigação para áreas experimentais / Development of an irrigation controller for experimental areas
Irrigation scheduling at experimental areas is determined by several factors, which are mainly related to features of each unit (container or bed) and criteria set by researchers. Many times the experimental areas are greenhouses and depending on the research may be necessary provide mechanisms for monitoring sensors and controlling actuators on each unit in

3. Fuzzy logic for structural system control
This paper provides some information and numerical tests that aims to investigate the use of a Fuzzy Controller applied to control systems. Some advantages are reported regarding the use of this controller, such as the characteristic ease of implementation due to its semantic feature in the statement of the control rules. On the other hand, it is also hypoth

4. 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

5. Sistema web didático para a supervisão de redes fieldbus
A evolução tecnológica dos sistemas de automação industrial tem sido norteada pelo dilema entre flexibilização e confiabilidade na integração entre equipamentos e sistemas supervisórios de controle. No entanto, são poucos os sistemas supervisórios cujas atribuições também abrangem o ensino do processo de comunicação que ocorre por trás dess

6. Automação do processo de soldagem a laser (Nd:YAG) para confecção das sementes de Iodo-125 utilizadas em braquiterapia / Development of an automation system for iodine-125 brachytherapy seed production by (Nd:YAG) laser welding
The aim of this work is to develop an automation system for iodine-125 radioactive seed production by (Nd:YAG) laser welding, which has been used successfully in Low Dose Rate (LDR) brachytherapy treatment. This small seed consists of a welded titanium capsule, with 0.8mm in diameter and 4.5mm in length, containing iodine-125 adsorbed onto a silver rod. The

7. 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

8. Eficiência energética em ambientes prediais utilizando rede sem fio Zigbee e Controle Fuzzy
This objective of this work is the wireless intelligent building automation focusing on the rational use of energy without prejudice to the thermal comfort. The wireless approach, in this work, could better target retro-fitting of buildings, a great HVAC (Heating, Ventilation and Air Conditioning) market share in Brazil. We used split air conditioners, power

12. Sistema supervisório de parâmetros de máquinas elétricas via TCP/IP e painel eletrônico de mensagens / Supervisory system of electric machines parameter via TCP/IP and message displays
The advent of internet simplified the comunication between remote systems, allowing the application of supervisory systems through the internet, mainly using the TCP/IP protocol. Although these systems have already been employed in industry, using the Programmer Logic Controller (PLCs) as driver, the implementation of any simple supervisory system could have
