Publication number: 20240030797Abstract: To control movement of a transport unit of a linear motor, a quality functional J(SG) with quality terms JTk(SG) is used as a function of manipulated variables (SG) of active drive coils. The quality functional J(SG) controlling movement of the transport unit along the stator is optimized with regard to the manipulated variable (SG) to determine optimal manipulated variables (SGopt) for the relevant time step of the control of movement, active drive coils are energized according to the determined optimal manipulated variables (SGopt), and at least two movement phases are provided during the movement of the transport unit along the stator. In the at least two movement phases, different quality functionals J(SG) are used for determining the optimal manipulated variables (SGopt), the different quality functionals J(SG) differing by the number k of the quality terms JTk(SG) used and/or by the quality terms JTk(SG) and/or by the weighting Factors kk.Type: ApplicationFiled: August 30, 2021Publication date: January 25, 2024Applicant: B&R INDUSTRIAL AUTOMATION GMBHInventors: Christian KRÄMER, Wolfgang KEMMETMÜLLER, Andreas KUGI, Andreas WEBER, Manuel PLAINER, Michael REINTHALER, Engelbert GRÜNBACHER

Patent number: 8970079Abstract: For an object on a bearing mounting having a magnetic bearing providing a magnetic field generally produced by an electromagnet, the bearing is regulated based on a position of the object relative to the bearing. The position of the object is determined by reference to an estimate of the inductance obtained using a least squares method, in which the electrical resistance of the bearing is taken into account. The resistance is subject to variations, for example due to temperature fluctuations; however, the electrical resistance can be estimated by regulating the inductance error, ?{circumflex over (L)}={circumflex over (L)}2,sLS?{circumflex over (L)}1,sLS down to zero, where the resistance adjustment facility may be a low-pass filter and an integration controller.Type: GrantFiled: March 8, 2011Date of Patent: March 3, 2015Assignee: Siemens AktiengesellschaftInventors: Georg Bachmaier, Christian Bachmann, Dominik Bergmann, Tobias Glück, Wolfgang Kemmetmüller, Andreas Kugi
