Patent number: 11720069Abstract: Provided is a method for the computer-assisted control of a technical system, in particular in a plant for generating energy, to achieve a predetermined technical behavior of the technical system, wherein an operating data set for controlling the system is provided. A system model for describing the mode of operation of the technical system is provided, wherein on the basis of the operating data set and on the basis of the system model, an optimization data set is determined by an optimization method. Based on the optimization data set, relevant parameters of the technical system that allow a more advantageous control of the technical system than other parameters of the technical system are selected using a selection method, wherein with the selected relevant parameters, a control method for the technical system is determined, wherein the technical system is controlled with the aid of the control method.Type: GrantFiled: October 11, 2018Date of Patent: August 8, 2023Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Daniel Hein, Alexander Hentschel, Steffen Udluft

Patent number: 11340564Abstract: In order to control a technical system, a system state of the technical system is continually detected. By a trained first control model, a subsequent state of the technical system is predicted on the basis of a sensed system state. Then, a distance value is determined for a distance between the predicted subsequent state and an actually occurring system state. Furthermore, a second control model is trained by the trained first control model to predict the distance value on the basis of a sensed system state and on the basis of a control action for controlling the technical system. A subsequent state predicted by the first control model is then modified on the basis of a distance value predicted by the trained second control model. The modified subsequent state is output in order to control the technical system.Type: GrantFiled: December 5, 2017Date of Patent: May 24, 2022Inventors: Alexander Hentschel, Steffen Udluft, Clemens Otte

Patent number: 10983485Abstract: In order to control a technical system, e.g. of a wind turbine, a temporal sequence of operating parameter values of the technical system that is continuously recorded and continuously converted into a sequence of filtered signal values by a trainable digital filter. The sequence of the filtered signal values is supplied to a mechanical learning routine which derives prediction values therefrom for a target operating parameter. The digital filter and the mechanical learning routine are trained to reduce a distance between derived prediction values and temporally corresponding, actually recorded values of the target operation parameter. The prediction values for controlling the technical system are then emitted.Type: GrantFiled: February 6, 2018Date of Patent: April 20, 2021Inventors: Alexander Hentschel, Markus Michael Geipel

Patent number: 10107205Abstract: The embodiments relate to a method for the computer-aided control and/or regulation of a technical system, particularly a power generation installation. The actions to be performed in the course of regulation or control are ascertained using a numerical optimization method (e.g., a particle swarm optimization). In this case, the numerical optimization method uses a predetermined simulation model that is used to predict states of the technical system and, on the basis thereof, to ascertain a measure of quality that reflects an optimization criterion for the operation of the technical system.Type: GrantFiled: August 5, 2014Date of Patent: October 23, 2018Assignee: Siemens AktiengesellschaftInventors: Siegmund Düll, Daniel Hein, Alexander Hentschel, Thomas Runkler, Steffen Udluft

Patent number: 9952566Abstract: A computer-implemented method for controlling and/or regulating a technical system, in which actions to be carried out on the technical system are first of all determined using an action selection rule which was determined through the learning of a data-driven model and, in particular, a neural network. On the basis of these actions a numerical optimization searches for actions which are better than the original actions according to an optimization criterion. If such actions are found, the technical system is regulated or controlled on the basis of these new actions, such that the corresponding actions are applied to the technical system in succession. The method is suitable, in particular, for regulating or controlling a gas turbine, wherein the actions are preferably optimized with respect to the criterion of low pollutant emission or low combustion chamber humming.Type: GrantFiled: August 23, 2013Date of Patent: April 24, 2018Assignee: Siemens AktiengesellschaftInventors: Siegmund Düll, Alexander Hentschel, Steffen Udluft

Patent number: 9926853Abstract: The invention concerns a method for the computerized control and/or regulation of a technical system. Within the context of the method according to the invention, an action-selection rule (PO?) is determined which has a low level of complexity and yet is well suited to the regulating and/or control of the technical system, there being used for determination of the action-selection rule (PO?) an evaluation measure (EM) which is determined on the basis of a distance measure and/or a reward measure and/or an action-selection rule evaluation method. The action-selection rule is then used to control and/or regulate the technical system. The method according to the invention has the advantage of the action-selection rule being comprehensible to a human expert. Preferably, the method according to the invention is used for regulating and/or controlling a gas turbine and/or a wind turbine.Type: GrantFiled: January 22, 2014Date of Patent: March 27, 2018Assignee: Siemens AktiengesellschaftInventors: Siegmund Düll, Alexander Hentschel, Steffen Udluft

Patent number: 9466032Abstract: A method for the computer-supported generation of a data-driven model of a technical system, in particular of a gas turbine or wind turbine, based on training data is disclosed. The data-driven model is preferably learned in regions of training data having a low data density. According to the invention, it is thus ensured that the data-driven model is generated for information-relevant regions of the training data. The data-driven model generated is used in a particularly preferred embodiment for calculating a suitable control and/or regulation model or monitoring model for the technical system. By determining optimization criteria, such as low pollutant emissions or low combustion dynamics of a gas turbine, the service life of the technical system in operation can be extended. The data model generated by the method according to the invention can furthermore be determined quickly and using low computing resources, since not all training data is used for learning the data-driven model.Type: GrantFiled: June 1, 2012Date of Patent: October 11, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Siegmund Düll, Alexander Hentschel, Volkmar Sterzing, Steffen Udluft
