Patent number: 7424337Abstract: In a method for increasing the control dynamics of a load driven by a direct drive via a driveshaft, a first transducer provides a first output signal indicating a first rotation speed, and a second transducer provides a second output signal indicating a second rotation speed. The direct drive is located between the first transducer and second transducer, with the second transducer being located in close proximity of the load. A mixed rotation speed is computed from a linear combination of the two rotation speed values, which is used as an actual control value of a controller of the direct drive. This method provides a very simple approach for increasing the control dynamics of a load driven by direct drive via a driveshaft.Type: GrantFiled: October 7, 2004Date of Patent: September 9, 2008Assignee: Siemens AktiengesellschaftInventors: Elmar Schäfers, Dietmar Stoiber, Hans-Peter Tröndle, Bernd Wedel

Patent number: 7152503Abstract: A device for compensating a torque produced on a movable axle in a machine tool or production machine by a gyrostatic effect includes a rotating useful machine system attached to the movable axle and producing a useful angular momentum, and a rotating machine counter-system attached to the axle and producing a counter angular momentum. The magnitude of the counter angular momentum is substantially identical to the magnitude of the useful angular momentum. The useful torque produced by a movement of the rotating useful machine system through a temporal change of the useful angular momentum is at least partially compensated by a counter-torque produced by a temporal change of the counter angular momentum. This arrangement represents a simple device for compensating a torque produced by the gyrostatic effect on a movable axle of machine tolls and production machines.Type: GrantFiled: November 12, 2004Date of Patent: December 26, 2006Assignee: Siemens AktiengesellschaftInventors: Gerhard Forster, Winfried Glück, Jens Hamann, Uwe Ladra, Elmar Schäfers, Dietmar Stoiber, Hans-Peter Tröndle, Bernd Wedel

Patent number: 7005826Abstract: A method for increasing the control response of a drive train of a machine tool or production machine with backlash and/or elasticity is described. A combined signal comprised of the motor speed measured on the motor and the load speed measured near the load of the drive train is supplied to a controller. The combined signal can generated in one of two ways: (1) by weighting the measured motor speed with a first multiplication factor (?), by weighting the measured load speed with a second multiplication factor (1??), and by subsequently adding the weighted motor speed to the weighted load speed; or (2) by first subtracting the measured load speed from the measured motor speed, then weighting the resulting difference by a multiplication factor ?, and finally adding the load speed to the weighted difference.Type: GrantFiled: January 22, 2004Date of Patent: February 28, 2006Assignee: Siemens AktiengesellschaftInventors: Bernhard Dirsch, Hans-Peter Tröndle

A combined signal comprised of the motor speed measured on the motor and the load speed measured near the load of the drive train is supplied to a controller. The combined signal can generated in one of two ways: (1) by weighting the measured motor speed with a first multiplication factor (&agr;), by weighting the measured load speed with a second multiplication factor (1−&agr;), and by subsequently adding the weighted motor speed to the weighted load speed; or (2) by first subtracting the measured load speed from the measured motor speed, then weighting the resulting difference by a multiplication factor &agr;, and finally adding the load speed to the weighted difference.Type: ApplicationFiled: January 22, 2004Publication date: August 5, 2004Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Bernhard Dirsch, Hans-Peter Trondle

Patent number: 6349642Abstract: In a conventional sheet-fed printing machine having a central drive, the dynamic positional deviation with respect to a setpoint value continually increases from printing unit to printing unit due to the elasticity (a vibratory multi-mass system). Thus, the precision is dependent on the number of printing units. A mechanical interconnection of the individual cylinders of the sheet-fed printing machine is partially removed and replaced by individual drives is, therefore, provided. In the multiple motor open-loop drive control described, the fault does not increase because in each printing unit, the torque is supplied separately, and all drives are closed-loop controlled using the same reference variable.Type: GrantFiled: February 1, 2000Date of Patent: February 26, 2002Assignee: Siemens AktiengesellschaftInventors: Jürgen Olomski, Hans-Peter Tröndle, Ralf Viefhaus

Patent number: 6347255Abstract: Various filter options in the current setpoint channel are available for optimal adjustment of a drive system to an elastomechanical system. The present method permits optimal adjustment of the speed controller through measurement of the speed control system by automatically determining possible parameters for a filter setting which may optionally be necessary. In a simulation calculation in the frequency range which relies on data from the measured system, a check is performed to determine whether the speed controller must be equipped with filters. In addition, the possible control parameters for the gain and the reset time of the speed controller are determined.Type: GrantFiled: December 18, 1998Date of Patent: February 12, 2002Assignee: Siemens AktiengesellschaftInventors: Roland Moser, Hans-Peter Tröndle

Patent number: 6266570Abstract: Standard, existing position measuring systems are used to determine and optimize operating accuracy. For this, in a positional measurement, path information on any desired number of axes is sampled over a predefinable measuring interval and stored. The acquired data are converted and prepared using signal processing measures, enabling conclusions to be drawn about the actual operating accuracy and about causes of inaccuracies.Type: GrantFiled: July 23, 1998Date of Patent: July 24, 2001Assignee: Siemens AGInventors: Günther Höcherl, Roland Moser, Hans-Peter Tröndle, Georg Wiegärtner

Patent number: 5353217Abstract: In a control system, especially a hydraulic screw-down control system for a roll stand, the controller output is acted upon by a pilot control value (v.sub.1.sup.*). At the same time, a reference value (x.sub.M ') is delivered to the controller via a subtractor as a setpoint value. The reference value (x.sub.m ') is determined in a model control loop based on the pilot controller. Parasitic response characteristics of the overall system are largely accounted for in the model control loop, so that on a time-averaged basis the controller is not activated.Type: GrantFiled: February 24, 1993Date of Patent: October 4, 1994Assignee: Siemens AktiengesellschaftInventors: Andre Berghs, Hans-Peter Trondle, Peter Hopf, Georg Bytomski, Hans-Joachim Felkl
