    摘要: A method for detecting a closing moment of a valve having a coil drive includes impressing an electrical voltage in the exciter coil to generate an exciter current through the coil, which attracts the movable armature and lifts the valve element off its valve seat. After the exciter current decays to zero, the voltage profile at the exciter coil is sampled and read out over time in the form of time value/voltage value pairs. The detected voltage values and time valves are transformed by the formation of a logarithm to form a transformed function. The transformed function is subsequently derived numerically with the formation of a derivation function. A transformed time value corresponding to the valve closing moment is detected based on the derivation function of a predetermined threshold value S being undershot, and the closing moment is calculated therefrom by inverse transformation.

    摘要: In at least some implementations, a method for monitoring a fluid injection system that has a fluid pump activated by a coil and a controller adapted to drive the coil with a driving voltage includes monitoring the evolution of current flowing through the coil and the evolution of the time derivative of said current, and monitoring two successive zero crossings of the time derivative of the current flowing through the coil. The method provides an easy and cost-efficient way to discriminate various operating states of a fluid injection system including a coil/solenoid driven pump.

    摘要: The invention relates to a technique for discerning a status of an armature of a high-speed solenoid at any time during its operational cycle. In high speed solenoids, motion of an armature does not occur until after a finite and indeterminate lapse of time after application of a driving voltage.In the present invention, a pulsed driving voltage is used to drive the solenoid. A resultant current in a coil of the solenoid exhibits discontinuities in its rate of change when the armature moves. Occurrences of the discontinuities are used to produce control signals and coordinate operation of the solenoids and other controllable events. Occurrence of these discontinuities exactly correlates with armature motion. Consequently, time lapse between application of voltage and motion of the armature becomes inconsequential in design of a control system. In other words, control and coordination of operation of high-speed solenoids can be performed without consideration of uncertainties of the time lapse.In an exemplary illustration, the invention is applied to controlling speed of a turbine generator of a type used in space vehicles. High-speed solenoids are used to control bursts of hydrogen and oxygen flow into a combustion chamber of the turbine generator. Speed control is maintained by controlling a rate and duration of the bursts.

    摘要: A contactor having a separable conduction path, an actuator, a magnetic stator and armature, and a controller, is disclosed. The actuator is in mechanical communication with the separable conduction path, and the magnetic stator and magnetic armature are arranged in field communication with each other and with an excitation coil responsive to a coil current that serves to generate a magnetic field directed to traverse the stator and the armature. The controller has a processing circuit adapted to control the coil current in response to the current and voltage at the coil such that the coil current is controlled in response to the position and closing speed of the separable conduction path prior to the separable conduction path closing during an open-to-close action.

    摘要: A method of controlling an electromagnetic actuator having at least one electromagnet and an armature that can be moved by generated magnetic forces in a direction counter to the force of a restoring spring associated with the electromagnet, with the armature acting on a control element. The supply of current to the electromagnet in order to initiate the armature movement is effected by a linear regulator that regulates the coil current to a constant value, via a control member, prior to the anticipated impact of the armature on the pole face of the electromagnet. An identifying signal for armature impact is derived from changes in the control variable of the regulator (control current or control voltage) when the armature impacts during the constant-current phase.
