Publication number: 20240427306Abstract: A method parametrizes a model of a manufacturing machine of a manufacturing machine system. The manufacturing machine has at least one axis with a position-controlled drive, by which at least a first machine element can be adjusted relative to a second machine element. A maximum movement range, a maximum movement speed for the axis and a maximum electrical power that can be supplied to the drive of the axis are recorded, as boundary conditions for an identification run, in a control device comprised by the manufacturing machine system.Type: ApplicationFiled: July 7, 2022Publication date: December 26, 2024Applicant: Siemens AktiengesellschaftInventors: Gerhard FORSTER, Andreas KLOTZEK, Alexander KUBIK, Uwe LADRA, Philipp ROST, Elmar SCHÄFERS

Patent number: 11396192Abstract: A digital web printing press, control apparatus and method for operating the digital web printing press includes selecting a frequency for actuating a digital printing head at the frequency to output printing ink onto a print web, wherein a specified conveying speed for conveying the print web is ascertained based on the selected frequency and printing data, a motor driving a first roller and/or a motor driving a second roller is controlled based on the specified conveying speed such that the print web between the first roller and the second roller is conveyed at the specified conveying speed and the digital printing head at the selected frequency and activated based on the printing data such that the digital printing head is advantageously actuated at a selected, fixed frequency, and such that complex dynamic actuation of the digital printing head and an associated measurement and control system are eliminated.Type: GrantFiled: March 26, 2020Date of Patent: July 26, 2022Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Bernhard Dirsch, Philipp Rost, Elmar Schäfers

Patent number: 11353843Abstract: An actuator of a machine is controlled by a control device with a controller structure in a normal operating mode and a special operating mode. The control device determines from a position setpoint value and a position actual value a control signal for the actuator. In the normal operating mode, the setpoint values are determined using a utility program, and in the special operating mode by a system program that is different from the normal operating program. In the special operating mode, a frequency characteristic for the actuator is determined on the basis of the sequence of setpoint values and associated actual values, and an evaluation for the actuator and/or of the controller structure is performed using the frequency characteristic and parameters of the controller structure. Depending on the evaluation, a message is transmitted to an operator of the machine or to a computing device over a network.Type: GrantFiled: August 23, 2018Date of Patent: June 7, 2022Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Alexander Kubik, Philipp Rost, Elmar Schäfers, Torsten Schür, Stephen J.

Patent number: 11204595Abstract: A control device of a machine tool includes a position controller and a model of a position-controlled axis. The position controller receives a position setpoint value, a corresponding actual position value and a compensation value; determines therefrom a resulting value; determines based on the resulting value an actuating signal; and outputs the actuating signal to the position-controlled axis. The position and/or the orientation of the tool relative to the workpiece are adjusted based on the actuating signal. A sequence of successive control errors is stored, in a storage device and read out sequentially in accordance with a sequence of the position setpoint values and supplied to the model. The model determines from the read-out control error a respective compensation value which is then supplied to the position controller, while simulating the mechanically dynamic behavior of the position-controlled axis.Type: GrantFiled: August 3, 2018Date of Patent: December 21, 2021Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Philipp Rost, Elmar Schäfers, Jürgen Reiser

Patent number: 10539946Abstract: A closed-loop control device to control a system to be controlled includes a front node, back node, external tapping point, controller and compensating circuit. The compensating circuit has an inner node, frequency filter, front buffer and back buffer. The front node determines a difference; the back node supplies an external sum signal. A setting device automatically suppresses use of the output signal of the front buffer, supplies the back buffer and the back node with a first excitation signal as the compensation signal and detects a first result signal produced by the first excitation signal. The first result signal is one of the control difference, internal sum signal, output filtered signal of the frequency filter or output signal of the front buffer. The setting device evaluates the first excitation signal and the first result signal, sets a parameter of the frequency filter and the second propagation delay.Type: GrantFiled: May 11, 2017Date of Patent: January 21, 2020Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Markus Stephan Haschka, Philipp Rost, Elmar Schäfers, Torsten Schür, Björn Seelinger
