摘要： Method in which the current is measured inside an integrated PWM control circuit using at least one A/D converter which is likewise integrated in the circuit is described. The PWM controller is provided for the purpose of driving inductive loads and is arranged, in particular, in an electronic circuit of an electronic controller for a motor vehicle braking system. Before determining the actual current of the PWM controller, which is determined using the at least one A/D converter, the current is smoothed using a low-pass filter. A circuit arrangement for carrying out the above method and its use in electronic motor vehicle control systems is also described herein.

摘要： A method of controlling magnetic flux through an electromagnet, the magnetic force of the electromagnet or the relative position between the yoke and the armature of the electromagnet, such that from an electric voltage applied across an induction coil of the electromagnet and determined by an appropriate measurement method, and from an electric current flowing through the induction coil and also determined by an appropriate measurement method, an actual value of the magnetic flux, the magnetic force or the relative position is calculated. The determined actual value is compared with a specified nominal value and as a function of the difference between the actual and the nominal values, the voltage applied across the induction coil and/or the current flowing through the induction coil is/are adapted such that the actual magnetic flux or magnetic force or relative position value approaches the related nominal value.

摘要： An electromagnetic actuator includes a stator assembly mounted to a center pole formed of material having high magnetic permeability and functions as a return path for the magnetic field generated when current is passed through coils in the stator assembly. When current is applied to one or more coils within the stator assembly, a magnetic field is generated that interacts with a magnetic field generated by one or more magnets disposed within the armature assembly and causes the armature to move relative to the center pole thus, for example, opening or closing a valve.

摘要： An amperage control for an electrically operated valve having a coil. A process control apparatus generates a plurality of electrical operating data signals, each signal corresponding to an operating parameter of the valve. A valve control apparatus transmits voltage to the coil of the valve to control the operation of the valve, the valve control apparatus receiving at least one operating data signal generated by the process control apparatus. A current flow is created in the coil of the valve upon receiving voltage from the valve control apparatus. A current senses the flow of current in the electrically controlled valve, and creates an electrical signal responsive to the current flow in the coil of the valve. When the signal created by the current sensing apparatus is applied to the valve control apparatus, the valve control apparatus modifies the operation of the valve responsive to the signal created by the current sensing apparatus.

摘要： So that an actuator drive which holds an actuator element for actuating, for example, a charge cycle valve of an internal combustion engine, in a limit position by a coil, can be switched at the correct time into the other limit position, the energization of the coil is switched off a certain time period before the time at which the actuator element is to be released from the limit position. Here, the time period is selected as a function of the supply voltage of the actuator drive and/or of the coil current during the holding in the limit position. It is also possible to adapt the time period.

摘要： In the dither current power supply control method, in order to prevent occurrence of a difference between the target average current and the detected average current, which is caused when a medium current (I0) between a dither large current (I2) and a dither small current (I1) and a waveform average (Ia) of the dither current are different from each other depending on a response time difference (a−b) between a rise time (b) and a fall time (a) of the dither current, negative feedback control is carried out by using a command medium current corresponding to the target average current corrected by a correction parameter based on experimentally measured data, thereby suppressing occurrence of a transient fluctuation error by the negative feedback control, so that a highly precise and stable load current is acquired.

摘要： A fluid dispensing device and method for controlling the device are provided. The device includes a housing defining a fluid outlet. A valve controls the flow of fluid to the outlet. A sensor is configured to detect an object outside of and proximate to the housing. A solenoid is configured to move the valve between an open position and a closed position. A controller is configured to receive the output signal of the sensor, determine a characteristic of noise in the output signal such as a level of noise; adjust at least one of a sampling rate of the output signal and an amount of filtering of the output signal responsive to the characteristic of noise in the output signal, and transmit a control signal to the solenoid responsive to the output signal.
