    • In a control loop for regulating a combustion process in a plant (e.g., a power-generating plant, a waste incineration plant or a cement works) having a controlled system for converting material by way of the combustion process while supplying air, with at least one flame body being formed, and having at least one observation device for imaging the flame body, other sensors for determining the input data, at least one adjustment device that can be controlled by output data for supplying at least material and/or air, and a computer for evaluating the input data in relation to target values and for determining the output data by using a current process model, the computer has a feature extraction module that extracts features from the input data using an information measure. The features are informative for the target values, and are for use in an alternative process model.

    • A control loop, which is for regulating a process in a plant having a controlled system, comprises: at least one measuring device for recording observation values of the controlled system, at least one adjustment device for acting on the controlled system in response to the adjustment device being controlled by way of action values, and a regulator. The regulator is operative to provide the action values. The regulator being operative to provide the action values comprises the regulator being adapted for: predicting, by way of a process model and at least one probability distribution of the observation values, a set of distributions of probable future states of the system; evaluating the set of distributions of probable future states of the system using target values and/or distributions of the target values; and selecting at least one probability distribution of action values.

    • Material (G) is converted by a combustion process in a plant (1) while air (L) is supplied. The state of the system in the plant (1) is described by state variables (x, y) and is regulated at least by one control loop (3, 5, 7, 9). Groups of states (Z) are defined for at least one pair of correlated state variables (x, y), with the groups being comparable as regards changes (dx/dt, dy/dt) of the correlated state variables (x, y). Each group of comparable states (Z) is characterized, as regards their transition functions, by parameters (Kp, Tn, Tv) of a standard controller. In the event of changes in the state of the system in the plant (1), the closest groups of comparable states (Z) are selected, and their transition functions, characterized by the parameters (Kp, Tn, Tv), are used for the purposes of regulation the system.
