Abstract

método de processo de controle, método de orientação de operação, método de operação de um alto-forno, método de produção de metal quente e aparelho de controle de um processo. um método de controle de um processo inclui uma etapa de cálculo de resposta livre que calcula as respostas livres em um caso em que as quantidades de operação de todas as variáveis manipuladas são constantes por um período predeterminado de um tempo atual, uma primeira etapa de cálculo de resposta que calcula as primeiras respostas em um caso em que uma quantidade de operação de uma primeira variável manipulada entre as variáveis manipuladas é alterada na etapa para o período predeterminado, uma segunda etapa de cálculo de resposta que calcula as segundas respostas em um caso em que uma quantidade de operação de uma segunda variável manipulada diferente da primeira variável manipulada entre variáveis manipuladas são alteradas na etapa simultaneamente com a quantidade de operação da primeira variável manipulada para o período predeterminado e uma etapa de determinação de quantidade de operação que determina as quantidades de operação das variáveis manipuladas de acordo com as respostas livres, as primeiras respostas e as segundas respostas.
