Publication number: 20230045807Abstract: A method controls the current output of a battery for driving a rail vehicle. A battery actual current Ibat,ist passes via a converter to an asynchronous motor, being a drive for the vehicle. The battery actual current Ibat,ist is set by control circuits as a function of a feedforward control torque Mff and a specified torque Mtf. The feedforward control torque Mff is calculated using a transfer function Hsys(z), which maps the torque setpoint value Msoll onto the battery actual current Ibat,ist as follows: Ibat(z) Hsys(z) Msoll(z). Accordingly, a zero-point z=znmp, which lies outside the unit circle, is determined by the transfer function Hsys(z). The feedforward control torque Mff is calculated as follows: Mff(z) Ibat,neu(z)/(Hsys(z) z) where: Ibat,neu(z)=Ibat,ideal(z) Ibat,ideal(z=znmp) where: Ibat,neu[n]=Ibat,ideal[n] for all n>0, so that pole point/zero point cancellation is reached by z=znmp at the battery ideal current.Type: ApplicationFiled: November 25, 2020Publication date: February 16, 2023Inventor: Wolfgang Hoffmann

Patent number: 6698329Abstract: A method for replacing a fuse casing (4), which is riveted to the casing (2) of an active component (1) containing an explosive charge (3). The new fuse casing (4) laser-welded to the remaining rivet parts (5) of the active component casing (2). Welding filler materials are used to attach the new fuse casing (4) easily and securely to the active component casing (2), such that the connection can withstand even high firing accelerations, without this resulting in impermissibly high thermal stress to the explosive charge (3) in the active component. Welding powders (7) or welding pastes can be used as welding filler materials, which are inserted into gaps (8) remaining between the remaining rivet parts (5) and the bores (6) in the fuse casing (4) before the remaining rivet parts (5) are welded to the fuse casing (4). Also used are discs (9) that cover the bore holes (6) in the fuse casing (4). The disks are placed onto the frontal faces of the remaining rivet parts (5) and are welded to these.Type: GrantFiled: July 2, 2002Date of Patent: March 2, 2004Assignee: Rheinmetall W & M GmbHInventors: Wolfgang Hoffmann, Wolfgang Schiller, Wolfgang Schmidt

Patent number: 6456990Abstract: A method for transforming a fuzzy logic system into a neural network, where, in order to simulate membership functions, sigmoid functions are linked together in such a way that, even after the optimization of the neural network, back-transformation of the neural network into a, fuzzy logic system is possible. The advantage of the method described is that a fuzzy logic system can be transformed, in particular component by component, into a neural network and the latter can then be optimized as a whole, i.e. all the components together. The possibility of back-transforming the trained neural network ultimately means that an optimized fuzzy logic system can be obtained. This advantageously makes it possible to use, in particular, standardized fuzzy system software for describing the optimized fuzzy logic system.Type: GrantFiled: November 22, 1999Date of Patent: September 24, 2002Assignee: Siemens AktiengesellschaftInventors: Wolfgang Hoffmann, Erik Schwulera

Patent number: 6405652Abstract: A projectile includes a stabilizing band mounted on a rear projectile portion and having a folded state and a deployed state and a fuze assembly accommodated in the projectile. The fuze assembly includes a firing pin carrier supported for motion parallel to the longitudinal axis of the projectile; a firing pin secured to the firing pin carrier; a slide supported for motion transversely to the projectile axis and having a safety position and a firing position; and a detonator mounted on the slide. The detonator is out of alignment with the firing pin in the safety position of the slide and is in alignment with the firing pin in the firing position of the slide. A force-transmitting component is attached to the stabilizing band and the slide for moving the slide from the safety position into the firing position by a force generated by a motion of the stabilizing band from its folded state into its deployed state.Type: GrantFiled: April 17, 2000Date of Patent: June 18, 2002Assignee: Rheinmetall W & M GmbHInventors: Wolfgang Hoffmann, Michael Günther, Tobias Zerbe

Patent number: 6381591Abstract: A method for transformation of fuzzy logic (FS) into a neural network (NN), in which, in order to form a defuzzified output value (y2) from normalized single-element functions (F1 . . . Fm), the single-element functions (F1 . . . Fm) are each assigned a singleton position (A1 . . . Am) and at least one singleton weighting factor (R1 . . . Rn), those singleton weighting factors (R1 . . . Rn) which are assigned to the same single-element function (F1 . . . Fm) are additively linked, and the singleton weighting factors (R1 . . . Rn) and the additively linked singleton weighting factors (R1 . . . Rn) are weighted via the corresponding singleton positions (A1 . . . Am) and are additively linked in order to form the defuzzified output value (y2). One advantage of the method according to the invention is that the singleton positions (A1 . . .Type: GrantFiled: August 3, 1999Date of Patent: April 30, 2002Assignee: Siemens AktiengesellschaftInventors: Wolfgang Hoffmann, Erik Schwulera

The detonator is out of alignment with the firing pin in the safety position of the slide and is in alignment with the firing pin in the firing position of the slide. A holding shell is positioned in the projectile and is exposed to a force of an air current during projectile flight for causing the holding shell to fly off the projectile. A force-transmitting component connects the holding shell with the slide for displacing the slide from the safety position into the firing position upon movement of the holding shell away from the projectile.Type: GrantFiled: April 17, 2000Date of Patent: November 20, 2001Assignee: Rheinmetall W & M GmbHInventors: Wolfgang Hoffmann, Karlheinz Roosmann

Patent number: 5900791Abstract: An armature-mounting arrangement for a hinged-armature relay includes a yoke (3), an armature (1) positioned at an end portion of the yoke, and an armature holding spring (2) which has at least one switching contact thereon and which is mechanically coupled to the armature. The armature holding spring is formed as one piece with a return spring (5) for the armature and also with spring hooks (4). Each of the spring hooks has a first portion (4a) lying substantially flat on an outer side of the armature and a second portion (4b) extending from the first portion about the armature and lying almost flat against an outer surface of the yoke. This armature-mounting arrangement is a particularly uncomplicated and cost effective structure and its operation is also not particularly sensitive to fabrication tolerances of the armature and the yoke.Type: GrantFiled: November 22, 1996Date of Patent: May 4, 1999Assignee: Hella KG Hueck & Co.Inventors: Wolfgang Hoffmann, Andre Koerner, Maik Zimmer
