摘要： An improved method for controlling the landing velocity of an armature in an electromechanical actuator, such as a fuel injector, fuel pressure regulator, or engine valve actuator is provided. The position and velocity of an armature during a stroke is dynamically estimated by calculating the inductance and rate of change of inductance of the actuator coil in real-time as the armature moves through its stroke, compensating for non-linear permeability and magnetization effects due to changing gap, temperature, magnetic material properties or magnetic architecture, normalizing the calculated inductance value at the end of a stroke (zero gap), and mapping the value of normalized inductance to correspond to an armature position by an algebraic transformation. Inductance may be used directly as a position variable without mapping it to units of position. Rate of change of inductance may be used as a rate variable without mapping it to units of velocity.

摘要： A solenoid driver (10) capable of detecting the operational status of a solenoid (12) including the position of an armature within a solenoid coil and an operational method. The solenoid driver (10) generates a first solenoid current within the solenoid (12) and measures a first decay time t1. The first solenoid current is insufficient to pull the armature into the coil of the solenoid (12). A comparator circuit (22) continuously monitors the solenoid current and initiates a timer within a counter circuit (34) to compute the first current decay time. A second solenoid current is generated within the solenoid (12) that is sufficient to pull the armature into the coil of the solenoid (12). The second solenoid current is turned off and a second decay time t2 is measured. The decay times are stored in storage registers (R1, R2) within a controller (36). The controller (36) compares the measured decay times with stored values and outputs the armature position information over a communications bus (34).

摘要： A varying voltage is applied across a coil (20) of a contactor (12). The varying voltage has a characteristic (frequency) which varies as a function of the position of the armature (16). The varying voltage is transmitted to a coupler (42) which transmits information to a controller. The coupler may include one or more light sources (LEDs) (50 and/or 52) which are sequentially energized and de-energized to sequentially render a phototransistor (54) conducting and nonconducting. The frequency of the output from the coupler (42) corresponds to the frequency at which the phototransistor (54) is changed between the conducting and nonconducting conditions. A controller (32) determines whether the frequency of the output from the coupler (42) corresponds to the intended position of the armature (16) of the contactor (12) or to an unintended position by comparing the frequency of the output from the coupler to known frequencies for various positions of the armature.

摘要： In a controlled force variable reluctance position-sensing actuator having a moving element operated by a solenoid (84) the current in the solenoid (84) is controlled by a signal representative of the flux density in the magnetic circuit of the actuator. The signal is produced by a Hall effect device (83) placed in the magnetic circuit, and the current in the solenoid is controlled by controlling its duty cycle although continuous control of the current may also be employed. The position of the moving element is monitored and selectively controlled in response to measured electric and magnetic parameters of the actuator. Alternative embodiments are provided for a constant force actuator, an actuator whose force-displacement characteristic is altered, and an actuator in which the force may be selectively controlled.

摘要： A control of an electromagnetically driven reciprocating piston influences the speed of a magnet armature by switching the voltage supplied to the electromagnet dependent on the position of the magnet armature. In the process, the position of the magnet armature should not be measured but rather determined from state variables of the electromagnet. This is achieved in that a processor (11) calculates the electric resistance of the magnet coil (5) from the electric voltage values and electric current values measured by the measuring device (13), calculates the temporal change of the linked magnetic flux in the electromagnet (2) from the electric voltage, the electric current, and the electric resistance of the magnet coil (5), calculates the linked magnetic flux in the electromagnet (2) from an older magnetic flux and the temporal change, determines the position of the magnet armature (7) from the linked magnetic flux in the electromagnet (2) and the electric current flowing through the magnet coil (5), and switches the electric voltage at the magnet coil (5) by means of the switch device (12) depending on the position of the magnet armature (7). Reciprocal piston pumps of the aforementioned type and the electric control thereof are used to pump and/or meter fuel and reagents in vehicles and mobile work machines.
