Patent number: 10338542Abstract: An interactive assistance system and method for computer-aided control optimization for a technical system is provided. For example, a gas or wind turbine, in particular for optimizing the action sequence or the control variables of the plant (e.g. gas supply, compression), wherein an input terminal is provided for reading at least one status parameter providing a first system status of the technical system, and at least one setting parameter for adapting a reward function. A simulation module having a pre-trained neuronal network, simulating the plant, serves to simulate an action sequence on the technical system, starting from the first system status and to the prediction of the resulting statuses of the technical system.Type: GrantFiled: May 5, 2015Date of Patent: July 2, 2019Assignee: Siemens AktiengesellschaftInventors: Siegmund Düll, Alexander Hentschel, Jatinder P.

Publication number: 20180237878Abstract: Disclosed are hot forming systems and apparatuses for metalworking components from micro-alloyed press hardened steel (PHS), methods for operating such systems/apparatuses, processes for hot forming components from micro-alloyed PHS, and components formed from such processes. A method of hot forming components from steel is disclosed. The method includes transferring a workpiece formed from a PHS micro-alloyed with niobium (e.g., 0.02-0.1 wt % Nb) to a furnace, e.g., via material handling robot. The workpiece is then heated to a peak furnace temperature and during a furnace time (e.g., total ramp and soak time) selected from a pentagon having heating time and temperature coordinates of: A (about 2 minutes, about 940° C.), B (about 2 minutes, about 1100° C.), C (about 3.5 minutes, about 1100° C.), D (about 5 minutes, about 975° C.), and E (about 5 minutes, about 940° C.). The heated workpiece is then transferred to a hot forming apparatus.Type: ApplicationFiled: February 17, 2017Publication date: August 23, 2018Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Jianfeng Wang, Charles M.

Patent number: 10036328Abstract: 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.Type: GrantFiled: January 22, 2014Date of Patent: July 31, 2018Assignee: Siemens AktiengesellschaftInventors: Hans-Gerd Brummel, Siegmund Düll, Jatinder P.

Patent number: 7481061Abstract: A method of controlling fuel flow to a combustor (18) of a gas turbine engine (10) during startup of the engine includes determining a relationship between Cv and valve position for a flow control valve (e.g., 24) in a fuel supply (20) to the combustor as a function of at least one real time parameter of fuel (30) in the fuel supply. The method also includes determining a value of the at least one parameter of the fuel before initiating a flow of the fuel to the combustor, and then calculating a first actual Cv value for the flow control valve at a target flow rate using the determined value of the parameter. The method then includes positioning the flow control valve to a first position corresponding to the actual Cv value based upon the determined relationship between Cv and valve position, and initiating the flow of fuel to the combustor through the flow control valve.Type: GrantFiled: November 10, 2005Date of Patent: January 27, 2009Assignee: Siemens Energy, Inc.Inventors: Satish B.
