Abstract

Patente de Invenção: <B>"MéTODO DE CONTROLE PREDIZìVEL DE MODELO NãO-LINEAR PARA CONTROLAR UM REATOR DE FASE GASOSA INCLUINDO UM PROCESSO E UM FILTRO DE RUìDO RáPIDO PARA O MESMO"<D>. Um método de controlar um reator químico tal como um reator de fase gasosa utilizando um controle predizível não-linear que inclui as etapas para gerar uma pluralidade de sinais de sinais representando um estado atual do reator químico e refletindo um respectivo constituinte de reagentes no reator químico, calcular um estado futuro do reator químico responsivo à pluralidade de sinais e reportado à retenção em massa dos reagentes no reator químico, e controlando pelo menos um parâmetro relacionado com o reator químico de modo a controlar o estado futuro do reator químico. Eventos de controle espúrios devido a ruído no sensor ou sinais de saída do controlador de preferência são minimizados pelo filtrar estes sinais utilizando uma sub-rotina de filtro de sinal-N.
