    摘要: A method and an assembly for controlling an internal combustion engine having multiple burners is provided. Combustion measurement data is collected in a burner-specific manner for each burner and assigned to a burner identification identifying the respective burner. Performance measurement data of the internal combustion engine is also collected and used to determine a performance value. A machine learning model is trained by means of the combustion measurement data, the associated burner identifications and the performance measurement data, to generate burner-specific control data which optimizes the performance value when the burners are actuated in a burner-specific manner using the control data. The control data generated by the trained machine learning model is output for the burner-specific actuation of the burners.

    摘要: A method for computer-assisted monitoring of an electrical energy-generating installation, in which output variables (y(t)) of the installation are prognosticated using a data-driven model (NN) based on corresponding input variables (x(t)). A confidence measurement (C(t)) is determined for respective input variables (x(t)), using one or more density estimators (DE), this measurement being higher, the greater the similarity of the input variables (x(t)) to known input variables from training data with which the data-driven model (NN) and the density estimator (DE) are taught. Based thereon, an average weighted deviation (E(t)) is determined between the prognosticated output variables (y(t)) and the output variables (y0(t)) actually occurring. If the average weighted deviation (y(t)) exceeds a predetermined threshold (ETh) successive times, an error in operation is detected and an alarm is issued.

    摘要: The invention concerns a method for the computerized control and/or regulation of a technical system (T). Within the context of the method according to the invention, there is implemented in a preset regulating process (CO1, CO2) an exploration rule (EP) by means of which new, as yet unknown, states (x) of the technical system (T) are started, a simulation model (SM) of the technical system (T) checking whether the actions (a2) of the exploration rule (EP) lead to sequential states (x′) lying within predetermined thresholds. Only in that case is the corresponding action (a2) performed according to the exploration rule (EP) on the technical system. The method according to the invention enables new states to be explored within the framework of the operation of a technical system, it being ensured through checking of appropriate thresholds that the exploration is carried out imperceptibly and does not lead to incorrect operation of the technical system. The method according to the invention is suitable in particular for controlling or regulating gas turbines or wind turbines.
