Abstract

MéTODO PARA MONITORAR OPERAçãO DE UMA MALHA DE CONTROLE EM UMA INSTALAçãO DE PROCESSO, MEIO TANGìVEL, SISTEMA PARA MONITORAR OPERAçãO DE UMA MALHA DE CONTROLE EM UMA INSTALAçãO DE PROCESSO, E, MéTODO PARA FACILITAR A OPERAçãO DE MONITORAMENTO DE NO MìNIMO UMA PORçãO DE UMA INSTALAçãO DE PROCESSO. Em um método para monitorar uma malha de controle em uma instalação de processo, dados de ganho de processo associados com uma malha de controle podem ser coletados. Os dados de ganho de processo coletados podem ser utilizados para determinar um comportamento de ganho de processo esperado. Por exemplo, valores esperados de uma variável de processo para dados valores de uma carga variável podem ser determinados.Como um outro exemplo, mudanças esperadas em uma variável de processo para dadas mudanças em uma carga variável podem ser determinadas. Então, durante operação da malha de controle, o ganho de processo pode ser monitorado. Se o ganho de processo desvia substancialmente do comportamento esperado, isto pode indicar uma situação anormal associada com a malha de controle.
