APPARATUS AND METHOD FOR CONTROLLING AT LEAST ONE OPERATIONAL PARAMETER OF A PLANT

摘要

A method for controlling at least one operational parameter of a plant (1) having a combustion unit (3) can include the estimation of a status of at least one operational variable of the plant, so as to confirm an estimated value for the operational variable. For each operational variable, the estimated value for the operational variable can be compared with a measured value of the operational variable to determine an uncertainty value on the basis of a difference in a value between the measured value and the estimated value for the operational variable. A control signal can be generated on the basis of a reference signal, the measured value, and the deviation value for sending the same to at least one element of the plant (1) for controlling a process of the plant (1).
