In a control method, the first controlled variable is made to coincide with a predetermined controlled variable set point. A relation variable representing the relationship between second controlled variables which are designated in advance from measured second controlled variables different from the first controlled variable so as to maintain a predetermined relationship is calculated. A control actuator is so controlled as to make the calculated relation variable coincide with a predetermined relation variable set point. The difference between the calculated relation variable and a relation variable set point corresponding to the calculated relation variable is calculated. The calculated difference is added to the measured first controlled variable. A manipulated variable is calculated by performing feedback control calculation so as to make the sum coincide with the controlled variable set point. The calculated manipulated variable is output to a corresponding control actuator. A control apparatus is also disclosed. |
