Autores: Barbosa, Paulo Roberto; Seleghim Jr., Paulo
Resumo: The pneumatic conveying of solids in a gas stream is a recurrent process in petrochemical industries as well as in agricultural, food and mining. However, due to practical limitations the majority of existing systems have capacities ranging from 1 to 400 tones per hour over distances less than 1000 m, mainly because of high power demand per transported unit mass. A safe circuit with reduced power demand can be designed using non-conventional control techniques. This work describes a fuzzy controller implementation for a 45mm i.d. pneumatic conveying system used to transport Setaria italica seeds over a distance of 21 m. Data obtained in a previous study about gas-solid flow regime identification through a self-organizing neural network were used in the controller design. Two types of accidents were induced to qualify the controller performance in an imminent blockage situation. The results show a safe operation and a reduction in power demand when compared with classical non controlled transport.
