Abstract

"SISTEMA PARA INFERêNCIA EM LINHA DE PROPRIEDADES FìSICAS E QUìMICAS, SISTEMA PARA INFERêNCIA EM LINHA DE VARIáVEIS DE PROCESSO, E, SISTEMA DE CONTROLE EM LINHA" é descrito um sistema para inferência e controle, em linha, de propriedades físicas e químicas de polipropileno e seus copolímeros, o sistema compreendendo modelos para a inferência das propriedades físicas e químicas qua não são medidas continuamente e modelos relevantes para o controle dessas propriedades, da taxa de produção e da densidade do meio reacional. O sistema de controle descrito permite a maximização de taxa de produção e do rendimento do catalisador no processo produtivo.
