Publication number: 20240151279Abstract: A method for standstill control of a multi-body system (MKS) having at least one drive body and at least one friction body mechanically coupled to the drive body. A static friction acts on the friction body, a velocity of one of the bodies of the MKS is determined as measurement velocity subject to a measurement noise and converted in a dead zone element to a dead zone velocity. The dead zone velocity assumes the value of zero for values of the measurement velocity above a value of zero and below a positive dead zone limit, and assumes the value of the measurement velocity for values of the measurement velocity above the positive dead zone limit. The dead zone velocity is provided to a velocity controller as an actual velocity for controlling.Type: ApplicationFiled: November 7, 2023Publication date: May 9, 2024Applicant: B&R INDUSTRIAL AUTOMATION GMBHInventors: Joachim WEIßBACHER, Helmut HERZOG

Publication number: 20240088809Abstract: In order to simplify the starting-up of a transport device in the form of a long-stator linear motor, a thermal design and/or an electrical design and/or a mechanical design of the transport device is checked using a time course of the electrical control variable of the drive coils for producing a product flow, and, before starting-up, a transport device configuration having a thermal and/or electrical and/or mechanical configuration is changed if the product flow cannot be implemented due to the thermal design and/or electrical design and/or mechanical design.Type: ApplicationFiled: November 30, 2021Publication date: March 14, 2024Applicant: B&R INDUSTRIAL AUTOMATION GMBHInventors: Philipp WAGNER, Martin HAUDUM, Joachim WEIßBACHER

Patent number: 11241876Abstract: A method for controlling a drive of a machine having at least one first roll element, which rolls with a surface on a counter surface at least in subintervals of a revolution cycle with the action of a contact force under elastic deformation, that includes a speed correction method, which automatically compensates for deformation-related deviations of the peripheral velocity of the first roll element by way of an adaptation of the setpoint value for the velocity of the first roll element, and a retrospective method, which automatically compensates for deviations of the speed consistency of the first roll element within a revolution cycle by applying a correction signal determined from the curve of a control variable, in particular an actual velocity or actual position of the first roll element, in a preceding revolution cycle or in multiple preceding revolution cycles, are applied in combination.Type: GrantFiled: August 23, 2016Date of Patent: February 8, 2022Assignee: B&R INDUSTRIAL AUTOMATION GMBHInventors: Joachim Weissbacher, Robert Kickinger, Albert Tresens

Patent number: 10554111Abstract: In order to improve the adaptation of a long stator linear motor to requirements or conditions of individual transport units or of the transport track it is foreseen, that a movement profile is preset for the transport unit (Tx), which is followed by the transport unit (Tx), in doing so at least one system parameter of a model of the control system (21) is determined by means of a parameter estimation method, and the value of the system parameter over time is collected and from the variation over time a wear condition of the transport unit (Tx) and/or of the transport track is deduced.Type: GrantFiled: May 30, 2017Date of Patent: February 4, 2020Assignee: B&R INDUSTRIAL AUTOMATION GMBHInventors: Andreas Weber, Joachim Weissbacher
