摘要:
In a method and apparatus for controlling of a servo-drive, in particular of a solid state actuator in which the servo-drive is controlled during each control process by means of a two-point regulator (R2P), the two-point regulator (R2P) has a power signal (I) as control signal for actuation of the servo-drive. An upper switch point (PO) of the two-point controller (R2P) is allocated to one maximum power value (ÎOn) and a lower switch point (PU) of the two-point controller (R2P) is allocated to one minimum power value (ÎUm). The upper switch point (PO) and the lower switch point (PU) are established during the controlling process so that they are separated in pairs by at least a minimum default spacing (Dmin).

摘要:
In a method for reading and/or storing injector-specific data for controlling an injection system of an internal combustion engine, an injector is charged by a control unit according to a predeterminable voltage curve and, depending on the case, is discharged directly by the control unit or by a power element located on a data storage medium and the voltage is measured by the control unit and by the data storage medium. Dependent upon a predeterminable voltage curve, a predeterminable amount of data is stored or read on a memory unit of the data storage medium.

In order to store excess kinetic energy, an energy storage device and an operating method are described, in which the kinetic energy can be partially converted into electrical energy by a first electric machine using at least two electric machines arranged on a shaft and can be partially converted into additional kinetic energy, such as rotational energy, by a second electric machine. The method for energy storage of excess kinetic energy provides for converting kinetic energy partially into electric energy and partially into additional kinetic energy, such as rotational energy.
摘要:
A device for controlling a capacitive charge, in particular a piezoelectric actuator (2) has a signal generator (6) which is used to control a first end step (1) which is used to produce a discrete signal on the capacitive charge. device has a second end step (3, 4) which is used to generate a continuous signal on the capacitive charge. A counter-coupling of a deviation of an actual discrete signal is produced by a continuous signal required on the capacitive charge.

A power output stage for capacitive loads includes: an energy storage inductance, having one end connected to a reference potential and an opposite end connected on the input side to a power supply connection and on the output side to a secondary energy storage capacitance; a primary energy storage capacitance is connected upstream of the energy storage inductance on the input side, and connected on the input side via a primary switching element with a reference potential, and a secondary switching element connected in series with the secondary energy storage capacitance (4), characterized in that the input of the power output stage is clocked by an additional switch.
