Definitions

  • Electromagnetic actuators which essentially consist of at least an electromagnet and one to be actuated Actuator connected anchor exist when energized of the electromagnet against the force of a return spring is movable, have a high switching speed out.
  • d. H. with getting smaller Air gap between the pole face and armature, which is on the armature acting magnetic force increases progressively while the counterforce the return spring only grows linearly, so that the anchor with increasing speed on the Pole surface hits.
  • the anchor In addition to the noise, it can this leads to bouncing processes, d. H. the anchor hits first on the pole face, but then lifts at least for a short time until it finally comes fully to the plant. This can impair the function of the Actuator come what is particularly high in actuators Switching frequency can lead to considerable interference.
  • the invention has for its object an improved To create regulatory procedures that are electromagnetic Actuator of the type described in the introduction enables even with changing operating conditions or interference via a regulation of the energization of the electromagnet To guide the movement of the armature so that it has a low impact speed at its seat on the pole face to the system comes. Adequate holding power after impact the anchor on the pole face must be replaced by a corresponding regulated holding current can be specified via the controller.
  • this object is achieved by a method to control an electromagnetic actuator with the process steps specified in the claim.
  • the process takes advantage of the possibility that modern electronic Computing modules with a high computing speed have so that it is possible not only during the Switching the respective position and / or speed of movement to detect, but also a plurality of actuators to grasp with regard to their movement sequence, to process the required movement values and with yourself resulting deviations via a corresponding control intervention one for each actuator optimal execution of each switching cycle for each actuator to ensure.
  • a in the Control device stored map in which for generation of the target value for the current supply the required dependency the anchor speed specified via the anchor path and by recording the actual values of the armature movement with regard to Anchor path and speed disruptive factors caused by a Map-dependent change of the setpoint specification for the Current controller and thus the actual value for energizing the "catching" electromagnets and thus the magnetic energy feed can be performed so that the anchor with a Impact speed on the pole face to the system comes that only slightly above the ideal impact speed "Zero" is.
  • map in the sense of the invention includes both a single map and a system of maps that are suitable for a variety of operating states be valid.
  • a gas exchange valve GWV for a piston internal combustion engine shown schematically that with an electromagnetic actuator EMA as valve train is provided.
  • the EMA actuator essentially consists of a closing magnet 2.1 and an opening magnet 2.2, between which an anchor 1 against the force from here only schematically indicated return springs RF1 and RF2 accordingly the current supply to the electromagnet 2 is guided to move back and forth is.
  • the two possible switch positions of the Actuator-forming gas exchange valve GWV are used here by placing the armature on one of the two electromagnets 2 defined.
  • the armature 1 is shown in an intermediate position, after it has been switched off by opening the opening magnet 2.2 by the force of the assigned spring RF 2 in the direction of the closing magnet 2.1, d. H. is moved in the direction of the arrow.
  • the movement of the armature 1 is in each case by the energization the magnet 2 controlled. In the movement process shown In the direction of the arrow, this is done via a control the energization of the catching closing magnet 2.1, so that acts on the armature 1, a magnetic force against the Restoring force of the return spring RF1 on the closing magnet acts after the armature 1 moves through the central position went through.
  • the current is provided by the current regulator 3, the in turn, his commands for energization from an engine control device 4 receives. At least the switch-off signals 5 for the current is passed to the current regulator 3.
  • the actuator is only schematic here shown detection and / or measuring device 7 assigned.
  • the anchor path is detected as a signal in the measuring device 7, whereby this path detection is not necessarily carried out directly Path measurement must take place, but also via a derivative the anchor path can take place from other characteristics, as will be described in more detail below.
  • the path signal 8 obtained via the measuring device 7 and a signal obtained therefrom speed signal derived via a differentiation 9 10 is supplied to the engine control device 4.
  • the engine control device 4 For processing the path signal 8 and the speed signal 10 is the engine control device 4 with a map or a map system 11 with maps for several actuators provided in which the course of the speed via the anchor path based on empirical knowledge or based on given by calculations from the characteristic data of the actuator is.
  • the speed curve over the way is here designed to achieve the desirable low impact speed of less than 0.05 m / s. This through that The map of the predetermined speed curve is a curve assigned for a current target value.
  • Is the path signal 8 and the derived speed signal 10 in its corresponds to the actual course in the specification of the map the current target value of the specification by the map. However, there are deviations compared to the stored map in the dependency between speed signal and displacement signal, then the current target value is corresponding corrected.
  • the current target value 12 taking into account the recorded actual movement conditions on the actuator using the specified map 11 or a map system of the engine control device itself is corrected, it is possible on the movement behavior of the actuator acting disturbances.
  • the various processes can be used. For example, it is possible by recording the path-dependent Change in the restoring force of the return spring RF1 or RF2 via piezoelectric transducers supporting the return springs RF1 or RF2 are assigned a corresponding one Derive path signal and a speed signal.
  • the electromagnet it is possible to capture the changing direction of the course of the magnetic field lines the changing anchor position and thus the anchor path capture.
  • the electromagnet With an appropriate arrangement that can Main field, but also the stray field of the electromagnet measured and depend on the position of the anchor Changes in the anchor path are derived.
  • end position used here in relation to anchor 1 also applies to the positions the anchor occupies if the valve is in the presence of a valve clearance Seat reached.
  • the measured or reconstructed variables “path” and “speed” are addressed to a characteristic diagram, from which a current target value is taken directly, in such a way that the optimal current is determined based on a realistic actuator model which enables a touchdown speed of approximately 0.
  • this is done by numerically solving the differential equation system of the actuator model, by integrating backwards in time from the moment the armature touches down with a low touchdown speed (point A in the state space).
  • the value range of the current specification is run through in a sufficiently fine gradation, for each sensible speed v j at the path position s i-1 to obtain a current target value that leads safely to the starting point A.
  • An additional quality measure can be used to select an optimal value from several possible current target values.
  • map points After running through all possible current values you now have a new number of possible map points, which enable the final final state to be reached. These map points are the second in Figure 2 Column seen from the left. Now for each of these points started calculating backwards to the third column. People this point is now considered a new "desired state” and for each of these points will make sense for everyone Streams performed the backward calculation. So with everyone A “pre-state” s (i), v (j) is determined for each current, that at the appropriate current to the desired condition leads. So it is also possible that a "pre-state” at different currents to several valid “desired” Conditions. First of all in both map points the current as well as the "final state” that can be achieved with it or the desired state can be saved.
  • a quality measure can be determined, which is an evaluation of the Map point entries makes.
  • Such a measure of quality can, for example based on what is considered to be particularly useful Trajectory can be determined by the map (the less Deviation from the trajectory, the better the map entry). Or other criteria, such as a current to be changed as little as possible the final map entries are used.
