- a known actuator (DE 195 26 683 A1) has an actuator, which is designed as a gas exchange valve and one Actuator.
- the actuator has two electromagnets, between which each against the force of a restoring means holding an armature plate by switching off the coil current Electromagnets and switching on the coil current at the trap Electromagnet can be moved.
- the coil current each of the catching electromagnets is set to a predetermined one Catch value constant over a specified period of time held and then by a two-point controller with hysteresis regulates a hold value until the coil current is switched off becomes.
- the object of the invention is a method for control to create an actuator that the sound generation at Meeting of an anchor plate on an electromagnet reduced.
- the object is achieved by the features of patent claim 1.
- the solution is characterized in that during the Braking value is specified as the setpoint for the current by the current is causing a braking field that is a force generated that directed opposite to the acceleration force that acts on the anchor plate.
- the acceleration force is caused by the tension of the springs.
- the impact speed of the anchor plate is determined by the braking field reduced.
- the solution also has the advantage that wear on the actuator is reduced.
- the Time period T2 from the speed and a load size or from a speed of the anchor plate or the braking value depends on speed and load size or speed the anchor plate. This enables a targeted, asymmetrical adjustment of the rest position of the anchor plate, without the sound radiation when operating the actuator is increased. This is particularly useful when the actuator is an exhaust valve, as this is against the exhaust gas pressure in the Cylinder must be opened.
- An actuator 1 ( Figure 1) comprises an actuator 11 and an actuator 12, for example as a gas exchange valve and a shaft 121 and a plate 122 Has.
- the actuator 11 has a housing 111 in which a first and a second electromagnet are arranged.
- the first Electromagnet has a first core 112, in which in a annular groove a first coil 113 is embedded.
- the second electromagnet has a second core 114, in which in a second coil 115 is embedded in a further annular groove is.
- the first core 112 has a recess 116a that forms a guide for the shaft 121.
- the second core 114 has a further recess 116, which is also used as a guide for the Shaft 121 serves.
- An anchor plate 117 is in the housing 111 movable between the first core 112 and the second Core 114 arranged.
- a first spring 118a and a second Spring 118b tension the anchor plate 117 into a predetermined one Rest position R before.
- Actuator 1 is rigidly connected to a cylinder head 21.
- An intake passage 22, an exhaust passage 22a and a cylinder with a piston 24 are assigned to the cylinder head 21.
- the Piston 24 is connected to a crankshaft via a connecting rod 25 26 coupled.
- a control device 3 is provided, the signals from sensors detected and control signals for the actuator 1 generated.
- the sensors are a position transmitter 4, which has a position X the anchor plate 117 detects a first ammeter 5a, the detects the actual value I_AV1 of the current through the first coil 113, a second ammeter 5b, which has an actual value I_AV2 of Current detected by the second coil 115, a speed sensor 27, which detects the rotational speed N of the crankshaft 26, or a Load detection sensor 28, which is preferably an air mass meter or is a pressure sensor. In addition to the sensors mentioned there may also be other sensors.
- a comparator device 7 which depends on the detected position X and predetermined threshold values K1, K2, K3, K4 generates a pulse signal.
- the comparator device 7 has four analog threshold comparators, each at one of the threshold values K1, K2, K3, K4 their output signal to change. By logically linking the threshold comparators The pulse signal plotted in FIG. 5e then arises the comparator device.
- the threshold values K1, K2, K3, K4 ( Figure 5d) are, for example, the following relative Distance values that are related to the distance of the contact surface the armature plate 117 in the first electromagnet and the contact surface of the anchor plate 117 in the second Electromagnets: K1 at 5%, K2 at 20%, K3 at 80% and K4 at 95%.
- a timer 8 ( Figure 1), preferably as a so-called "CAPCOM" unit is formed, detects the pulse duration of the of the. Comparator device 7 generated pulse signal and directs the time periods T_C2, T_O2 assigned to the pulse durations as digital data to the control device 3.
- the time period T_C2 is a measure of the average speed of the anchor plate between the threshold values K3 and K4.
- the same as determined by the timer 8 Duration T_O2 is a measure of the first approximation average speed of the anchor plate 117 between the Thresholds K2 and K1.
- a circuit arrangement (FIG. 2) of the driver 6a, 6b has a first transistor 61 whose base connection is connected to an output of the control device 3 and to which the voltage signal U S11 is present. Furthermore, the circuit arrangement has a second transistor 62, the base connection of which is connected to the control device 3 and to which the voltage signal U S21 is present. The circuit arrangement also has a first diode 63, a second diode 64 and a capacitor 65.
- the first transistor 61 becomes conductive from the collector to the emitter. If a high voltage level is additionally present at the base transistor on the second transistor 62, the second transistor 62 also becomes conductive.
- the supply voltage U V then drops approximately at the first coil 113.
- the current I_AV1 through the coil 113 then increases until the entire supply voltage U V across the internal resistance of the first coil 113 drops. If a low voltage level is subsequently specified at the base-side connection of the first transistor 61, the transistor 61 blocks and the diode 63 becomes conductive as a freewheeling diode.
- the current I_AV1 through the coil then decreases.
- both the voltage level of the voltage signal U S11 and the voltage level of the voltage signal U S21 are switched from high to low, both the first diode 63 and the second diode 64 become conductive and the current through the first coil 113 is driven by the charge of the capacitor 75 is reduced considerably faster than if freewheeling is only effected via the first diode 63. This ensures a very rapid reduction in the current I_AV1 through the first coil 113.
- the circuit arrangement of driver 6b is analogous to the circuit arrangement shown in FIG. 2. The only difference is that the voltage signal U S12 is present at the base connection of the first transistor 61 and the voltage signal U S22 is applied to the base connection of the second transistor 62, and that the emitter of the first transistor 61 and the collector of the second transistor 62 are electrically conductive are connected to the second coil 115.

- the controlled variable of controller B7 is the Current through the first coil 113. The function of block B6 is described below with reference to FIG. 4.
- the difference between the setpoint I_SP1 determined in block B6 and the actual value I_AV1 of the current through the first coil 113 is the control difference of the controller B7 designed as a two-point controller with hysteresis.
- the manipulated variables of the controller B7 are the voltage signals U S11 and U S21 .
- FIG. 3 shows the block diagram as an example for the calculation of the control signals for the first coil 113.
- the control signals for the second coil that is to say the voltage signals U S12 , U S22, are calculated analogously, only the time periods T_C2, T_C2 * are to be replaced by the time periods T_O2, T_O2 *.
- the output variable of block B6 is then the setpoint I_SP2 of the current through the second coil 115, a controller B8, which has the same structure as the controller B7 has the current through the second coil 115 as a controlled variable and has the voltage signals U S12 and U S22 .
- FIG. 4 shows the state diagram of block B6 as an example for the calculation of the setpoint I_SP1 of the current through the first coil 113.

- condition Z2 is the setpoint I_SP1 the catch value I_F.
- a transition from state Z1 to state Z3 takes place if a condition E2 is fulfilled, namely that the setpoint X_SP of position X is equal to an open position O.
- the setpoint I_SP1 is equal to the zero value IN.
- a transition from state Z2 to state Z4 takes place if the length of time dt has increased since entering state Z2 is as a time period T0.
- the period T0 is either predefined or determined by recognizing the impact the anchor plate on the first electromagnet.
- the setpoint I_SP1 of the current through the first coil 113 the holding value I_H.
- the transition from the state Z4 takes place in a state Z5 if a condition E4, that the Soliwert X_SP the position X of the anchor plate 117 die Open position O is fulfilled.
- the setpoint I_SP1 of the current through the first coil 113 the zero value I_N.
- a transition from the state Z5 takes place in a state Z6 if the condition E5, that the length of time dt has increased since entering state Z5 is fulfilled as a time period T1.
- the time period is T1 predefined so that a transition from the state Z5 to the state Z6 occurs at the earliest when the anchor plate 117 begins to move away from the first electromagnet.
- the setpoint I_SP1 of the current through the first coil 113 the braking value I_B.
- the condition E6 for one Transition from state Z6 to state Z3 is that the The time dt since the state Z6 was taken is greater than the period T2.
- the setpoint is I_SP1 of the current through the first coil 113 is the zero value I_N.
- the Condition E7 for the transition from state Z3 to state Z2 is that the setpoint X_SP is the position of the anchor plate is equal to the closed position C.

- FIG. 5d shows the assigned position X of the anchor plate 117 plotted over time t.
- the setpoint value of the current through the first coil 113 is the hold value I_H.
- the holding value I_H is predetermined such that the force on the armature plate 117 caused by the current through the first coil 113 is sufficient to hold the armature plate in contact with the first electromagnet and, on the other hand, only slight heat losses occur.
- the zero value I_N is specified as the setpoint I_SP1 of the current through the first coil 113 for the time period T1.
- both the voltage signal U S11 and the voltage signal U S21 are set to a low level, so that the actual value I_AV1 of the current through the first coil drops very quickly to the zero value I_N.
- the braking value I_B is specified as the desired value of the current through the first coil 113 at a time t 2, namely for the time period T2.
- the rest position R can be predetermined asymmetrically to the contact surfaces of the anchor plate on the two electromagnets. This is advantageous if the actuator is designed as an exhaust valve, since the exhaust valve must be moved against the high internal cylinder pressure during the transition from the closed position C to the open position O.
- the time period T1 is preferably chosen so that the anchor plate is still close to the closed position at time t 2 (for example, it has only covered 3% of the distance between the closed and the open position). A very good braking effect on the anchor plate is achieved.
- the zero value I_N is again specified as the setpoint I_SP1 of the current through the first coil.
- the setpoint I_SP1 of the current through the first coil is given the catch value I_F, specifically for the period T0.
- the catch value I_F is specified as the setpoint I_SP2 of the current through the second coil 115.
- the time t 3 can also be in time after the time t 4 .
- the associated course of position X of the anchor plate shows that after time t 1 the anchor plate first remains in the closed position C and then moves with increasing speed in the direction of the open position O until the acceleration of anchor plate 117 is reduced from time t 2 and the anchor plate reaches the open position O at time t 5 .
- the invention is not based on the described embodiment limited.
- the process can be run as a program by a Microprocessor are processed. But it can also do the same by a logic circuit or by an analog circuit arrangement will be realized.
- the catch value I_F and / or the Hold value I_H and / or brake value I_B can also be fixed be preset values.
- the controller can also be designed, for example, as a single-point controller with a timing element or as a pulse width modulation controller.
- a particularly low sound radiation from the control device is achieved if the catch value I_F is additionally reduced, specifically for a period of time that depends on the difference between the setpoint T_C2 *, T_O2 * and the actual period T_C2, T_O2.
- the catch value is, for example, eight amperes, the hold value three amperes and the braking value ten amperes.
