Definitions
- the invention relates to an electromagnetic actuator having at least two coils, an armature and a drive or power electronics according to the preamble of claim 1 and a method for controlling such an actuator according to the preamble of claim 9.
- DE 103 10448 A1 discloses an electromagnetic actuator with two coils and one armature. By energizing the coils of the armature is moved in the axial direction.
- DE 199 10497 A1 describes a method in which the position of an armature in an actuator with a coil is detected by determining the differential inductance of the coil. For this purpose, during a current drop, the current fall time is determined as a time difference between two threshold values. The current fall time depends strongly on the resistance of the coil and this is temperature dependent.
- DE 100 33 923 A1 discloses a method in which the position of an armature is determined as a function of the mutual induction which causes the movement of an armature in a coil.
- the mutual induction depends on the speed of the anchor.
- the speed of the armature is highly dependent on the viscosity of the fluid.
- the viscosity of a fluid is also temperature-dependent.
- an actuator which consists of at least two coils, an armature and a drive or power electronics.
- the power electronics is connected to a logic unit and is controlled by them.
- the power electronics contain at least switches, which are turned on or off, whereby a current flow allows or is interrupted. About the switch, the two coils are energized.
- the armature can be displaced via the regulation of the current in the coils and / or the position of the armature can be measured.
- the armature is slidably mounted between the two coils and back and forth between two end positions, wherein the anchor can also assume intermediate positions. To each of the two coils, a measuring amplifier is connected, which measures the voltage curve across the coils over time.
- the measuring signals of the measuring amplifiers are forwarded to a differentiator.
- a third voltage profile is calculated from the measurement signals, which contains a maximum value that depends on the position of the armature. This is because the inductance of a coil increases when an armature is pushed into it. Since the resistance of a coil depends on its inductance, the armature position influences the voltage curve.
- the maximum value of the third voltage profile is detected by the logic unit and, depending on this, it calculates the armature position.
- the power electronics has 3 or 4 switches.
- the logic unit consists for example of a ⁇ -controller or ⁇ -processor.
- the replacement diagram of one of the at least two coils may be presented for AC considerations by a known L-C-R resonant circuit.
- a resonant circuit consists of a first and a two-parallel parallel connected AC resistors.
- the first AC resistance consists of a series connection of a model coil and an ohmic resistance, the second AC resistance of a series circuit of a capacitor and another ohmic resistance. Both AC resistances are dependent on the frequency of the excitation.
- the coils are acted upon by a sudden energizing with a voltage jump. This moment, the turn-on torque, can be described by applying the coils to an alternating current of infinitely high frequency (f ⁇ ⁇ ).
- the AC resistance of the model coils depends on their inductance. Since the inductance of a coil increases when an armature is immersed in it, the AC resistances of the model coils change depending on the armature position.
- the voltage curves at the two coils are measured via the measuring amplifiers. Now, if the coils suddenly loaded with a surging voltage and the anchor is not in the middle between the two coils, results in the two coils two different voltage waveforms. These are subtracted from each other in the subtractor, resulting in a curve with a maximum value corresponding to the anchor position.
- This third voltage profile is forwarded to the logic unit, which detects the maximum value. decision speaking the maximum value of the logic unit, the anchor position can be determined, for example by a comparison with a map.
- FIG. 1 schematic diagram of an actuator
- Fig. 2 Schematic diagram of an actuator with a permanent magnetic armature
- Fig. 3 Schematic diagram of an LCR resonant circuit
- Fig. 4 measured voltage waveforms on the two coils
- Fig. 5 calculated voltage waveform from the two coils.
- Fig. 1 shows an electromagnetic actuator, which consists of two coils 1, 2 and an armature 3.
- the armature 3 is slidably mounted between the two coils 1, 2.
- the input of the first coil 1 is connected to a first pole 5 of a voltage source 6.
- the output 7 of the first coil 1 can be connected either via a first switch 8 to the second pole 9 of the voltage source 6 or via a third switch 10 to the input 11 of the second coil 2.
- the input 11 of the second coil 2 can be connected to the first pole 5 of the voltage source 6 either via a second switch 12 or to the output 7 of the first coil 1 via the third switch 10.
- the three switches 8, 10, 12 form the power electronics of the actuator.
- the output 13 of the second coil 2 is in turn connectable to the second pole 9 of the voltage source 6.
- a respective measuring amplifier 14, 15 is connected with the input and output 4, 7 of the first coil 1 and the input and output 11, 13 of the second coil 2, a respective measuring amplifier 14, 15 is connected.
- the measuring amplifiers 14, 15 are connected to the difference former 16, which is connected to the logic unit 17, to which it in turn conducts data.
- the logic unit 17 controls the three switches 8, 10, 12.
- the three switches 8, 10, 12 are so controlled that either the armature 3 shifts, or the two coils 1, 2 are subjected to a voltage jump. If now of the logic unit 17 of the first and the second switch 8, 12 are driven so that they are open and at the same time the third switch 10 is closed, the two coils 1, 2 are subjected to a voltage jump. In this switch-on the position of the armature 3 is determined from the voltage waveform across the two coils 1, 2.
- FIG. 2 shows a further embodiment of an electromagnetic actuator, which consists of two coils 1, 2 and one armature 3. This is a permanent magnetic anchor.
- the two Spuleni, 2 are wound in opposite directions, the winding direction of a first coil 1 is thus opposite to the winding direction of the second coil 2.
- the input 4 of the first coil 1 can be connected to the first pole 5 either via the first switch 8 or to the second pole 9 of the voltage source 6 via the second switch 12.
- the output 7 of the first coil 1 is connected to the input 11 of the second coil 2.
- the output 13 of the second coil 2 can be connected either to the first pole 5 via a third switch 10 or to the second pole 9 of the voltage source 6 via the fourth switch 18.
- a respective measuring amplifier 14, 15 is connected with the input and output 4, 7 of the first coil 1 and the input and output 11, 13 of the second coil 2, a respective measuring amplifier 14, 15 is connected.
- the measuring amplifiers 14, 15 are furthermore connected to the differential former 16.
- the Differenzsentneri 6 passes data to the logic unit 17.
- the logic unit 17 controls the four switches 8, 10, 12, 18, which form the power electronics of the actuator. By controlling the power electronics, the armature 3 can be moved and at the same time its position can be measured.
- the inventive arrangement therefore, a position detection of an actuator is possible without the need for an extra sensor is used. In addition, the position measurement is possible during the switching operations.
- the voltage jump is switched in this embodiment by two switch positions. Either the first and fourth switches 8, 18, or the second and third switches 12, 10 are closed.
- the input 4 of the first coil 1 is connected to the first pole 5 of the voltage source 6 and the output 13 of the second coil 2 to the second pole 9 of the voltage source 6.
- the input 4 of the first coil 1 with the second pole 9 and the output 13 of the second coil 2 connected to the first pole 5 of the voltage source 6. Because the two Coils 1, 2 are connected directly to each other results in a voltage jump in both cases.
- the armature 3 is acted upon for adjustment with a pulse width modulated signal. Since the voltage is switched on and off again and again with such a signal, the coils 1, 2 are repeatedly subjected to a voltage jump. Thus, the position of the armature 3 can be determined at any time of the switching of the voltage signal.
- Fig. 3 shows the structure of a known LCR resonant circuit 27, with which the coils 1, 2 can be described upon application of an AC voltage.
- the input of the resonant circuit corresponds to the inputs 4, 11 of the coils.
- the output of the resonant circuit corresponds to the outputs 7, 13 of the two coils.
- the resonant circuit has two paths. The first path is described by the model coil 19 and a first ohmic resistor 20 and forms a first AC resistance 31.
- the second path is described by a capacitance 21 and a second ohmic resistance 22 and forms a second AC resistance 32.
- a first time 28 describes the switch-on time at which a voltage jump is applied to both coils 1, 2. This is modelly described by an alternating voltage with an infinitely high frequency (f ⁇ °°). As a result, the course of the voltages on the coils 1, 2 depends on the respective AC resistors 31, 32. Up to a second time 29 (eg 5 ms), a first voltage curve 23 rises to a maximum value and the second voltage curve drops to a minimum value. The course up to the first time 28 is based on the influence of the parasitic capacitances 22. These occur in principle due to the interaction between the individual turns of the windings.
- the AC resistance of a Capacity goes to zero at f ⁇ °°.
- a transient begins at the second time 29 and the current flows through the model coil 19 until a third time 30 (eg, 50 ms).
- the AC resistance 31 depends on the inductance of the model coil 19, which in turn depends on the position of the armature 3. The inductance is higher, the further an armature 3 is immersed in a coil.
- the transient is completed, and the voltage curves 23, 24 are determined only by the two ohmic resistors 20 of the two coils 1, 2.
- DC states prevail again.
- the DC resistances of the two coils 1, 2 are advantageously the same size, resulting in no difference between the two voltage curves 23, 24 results.
- the second voltage curve represents the voltage curve in the second coil 2.
- both measured voltage profiles 23, 24 are subtracted from each other. This results in a third voltage curve 25 corresponding to FIG. 5. From the maximum value 26 of the third voltage curve 25, the anchor position in the logic unit 17 is determined, for example, by a comparison with a characteristic map stored there.
