Claim Text:
1. A method for controlling a combustion process in a firing chamber of a fossil-fired steam generator, comprising: providing the firing chamber of the fossil-fired steam generator; determining an arbitrary first number of spatially resolved measured values of the combustion process in the firing chamber using a spatially resolving measurement system; converting, by a computer processor, the arbitrary first number of spatially resolved measured values into a second number, which is less the first number, of state variables using a variable transformation, supplying the state variables as actual values to the second number of control loops in corresponding controllers for closed-loop controlling; calculating setpoint deviations by the controller in order to identify deviations for corrective closed-loop control interventions in the combustion process; distributing manipulated variable changes in the control loops among a third number of actuating elements in an inverse transformation taking into account an optimization target wherein the distributing includes producing a control signal for each actuating element, controlling each of the actuating element using the control signal such that each of the actuating element is used for the corrective closed-loop control intervention in the combustion process, wherein the optimization target is defined as a setpoint value for the state variables, and wherein the first, second, and third numbers are natural numbers.
