Abstract
In a control loop for regulating a combustion process in a plant having a controlled system for converting material by way of the combustion, with at least one flame body being formed, the control loop having at least one observation device for imaging the flame body and further sensors to determine the state variables describing the state of the system in the plant, at least one regulator and/or a computer to evaluate the state variables and select suitable actions based on a process model, and adjustment devices for at least the supply of material and/or air that can be controlled by the actions, the process model provides specialized function approximators for various process dynamics, one of which function approximators is selected by a selector, and a regulator assigned to the selected function approximator is used to regulate the control loop.
