The derivation of the current command value requiring the dimensional map data can be performed with the two-dimensional map data, the map data can be reduced, and the necessary data storage area can be reduced.

Next, a second invention of the drive control method for a composite rotating electrical machine of the present invention will be described.
FIG. 3 is a block diagram for calculating a current command value according to the second aspect of the drive control method for a composite rotating electrical machine of the present invention. Assuming that one of the two rotors of the composite rotating electric machine is the rotor 1 and the other rotor is the rotor 2, the block diagram of FIG. 3 receives the torque τ1 of the rotor 1 and the torque τ2 of the rotor 2 as inputs. The D-axis current command value η1 · Id1 and the Q-axis current command value η1 · Iq1 of the rotor 1 and the D-axis current command value η2 · Id2 and the Q-axis current command value η2 · Iq2 of the rotor 2 are output. The internal components of this block diagram are composed of six look-up tables and four multipliers. Here, the functions of the respective lookup tables will be described. The lookup table 1 derives the current multiplication coefficient η1 of the rotor 1, and the lookup table 2 derives the current multiplication coefficient η2 of the rotor 2. The look-up table 3 shows the D-axis current command value of the rotor 1, the look-up table 4 shows the Q-axis current command value of the rotor 1, and the look-up table 5 shows the D-axis current command value of the rotor 2.

  In the example shown in FIG. 3, the D-axis current command value Id1 of the rotor 1 obtained from the look-up table 3 to which the torque τ1 of the rotor 1 is connected, the look to which the torque τ1 of the rotor 1 and the torque τ2 of the rotor 2 are connected. The current multiplication coefficient η1 of the rotor 1 obtained from the up table 1 is connected to a multiplier, and the D-axis current command value η1 · Id1 of the rotor 1 is calculated.

  At this time, the current command value that is the basis of one rotor of the composite rotating electrical machine is a conventional 4 by using a look-up table in which the torque command value and the rotation speed of the other rotor are set to zero. The derivation of the current command value requiring the dimensional map data can be performed with the two-dimensional map data, the map data can be reduced, and the necessary data storage area can be reduced.

Next, a third aspect of the drive control method for the composite rotating electrical machine of the present invention will be described.
FIG. 4 is a block diagram for calculating a current command value according to the third aspect of the drive control method for a composite rotating electrical machine of the present invention. If one of the two rotors of the composite rotating electrical machine is the rotor 1 and the other rotor is the rotor 2, the block diagram of FIG. 4 receives the torque τ1 of the rotor 1 and the torque τ2 of the rotor 2 as inputs. The D-axis current command value η1 · Id1 and Q-axis current command value η1 · Iq1 of the rotor 1 and the D-axis current command value η2 · Id2 and the Q-axis current command value η2 · Iq2 of the rotor 2 are output. Further, the internal components of this block diagram are composed of four lookup tables. Here, the function of each look-up table will be described. The look-up table 1 shows the D-axis current command value of the rotor 1, the look-up table 2 shows the Q-axis current command value of the rotor 1, and the look-up table 3. The D-axis current command value for the rotor 2 is derived, and the lookup table 4 is for deriving the Q-axis current command value for the rotor 2.

  In the example shown in FIG. 4, the D-axis current command value Id1 of the rotor 1 is calculated from the look-up table 1 to which the torque τ1 of the rotor 1 is connected. From the look-up table 2 to which the torque τ1 of the rotor 1 is connected, the Q-axis current command value Iq1 of the rotor 1 is calculated. From the look-up table 3 to which the torque τ2 of the rotor 2 is connected, the D-axis current command value Id2 of the rotor 2 is calculated. A Q-axis current command value Iq2 of the rotor 2 is calculated from the look-up table 4 to which the torque τ2 of the rotor 2 is connected.

  At this time, the current command value that is the basis of one rotor of the composite rotating electrical machine is a conventional 4 by using a torque command value of the other rotor and a look-up table having values when the rotation speed is zero. The derivation of the current command value requiring the dimensional map data can be performed with the two-dimensional map data, the map data can be reduced, and the necessary data storage area can be reduced.

  Next, as a preferred example of the drive control method for the composite rotating electrical machine according to the first to third aspects of the present invention described above, the other rotor is used as a current command value that is the basis of one rotor of the composite rotating electrical machine. An example in which the torque command and the value when the rotation speed is zero will be described.

  FIGS. 5A and 5B are diagrams for explaining an example of a preferred example of the drive control method for the composite rotating electrical machine according to the present invention. 5A and 5B, a look for deriving the Q-axis current command value Iq1 of the rotor 1 when one rotor of the composite rotating electric machine is the rotor 1 and the other rotor is the rotor 2. An up table is shown. FIG. 5A is a lookup table for deriving the Q-axis current command value Iq1 of the rotor 1 when only the rotor 1 is driven. FIG. 5 (b) shows a case where the composite rotating electrical machine is driven with a composite current, and the Q-axis current command value Iq1 of the rotor 1 when the torque τ2 of the rotor 2 is τ2 >> τ1 and the rotational speed N2 is an arbitrary rotational speed. This is a lookup table to be derived. In the hatched portion of FIG. 5B, the ratio of the torque τ1 of the rotor 1 to the torque τ2 of the rotor 2 becomes very small. In this case, it can be seen that the current command value of the rotor 1 requires a larger current than the current command value in the case of single driving in FIG. Normally, the HEV motor has a wide range of acceleration / deceleration in HEV and is often driven only on one side, so that it is easy to adapt each rotor current command value of the composite rotating electrical machine.

  Next, as a preferred example of the drive control method for the composite rotating electrical machine according to the first to second inventions of the present invention described above, the coefficient obtained from the torque command values of the two rotors is such that the torque ratio of each rotor is large. An example in which the torque command value input to the rotor with a small torque will diverge infinitely when it approaches zero will be described.

  FIG. 6 is a diagram for explaining another example of a preferred example of the drive control method for the composite rotating electrical machine of the present invention. FIG. 6 shows a look-up table for deriving a current multiplication factor η1 of the current command value of the rotor 1 when one rotor of the composite rotating electric machine is the rotor 1 and the other rotor is the rotor 2. . In the hatched portion, the motor torque characteristic is a non-linear region. In this case, the current multiplication coefficient η1 with respect to the current command value of the rotor 1 has a property of converging to infinity. With this effect, the current command value of the rotor 1 can be set to a very large value with respect to the basic current command value for the torque τ1 or the rotational speed N1 when the rotor 1 is independently driven. Therefore, it is possible to obtain a more accurate torque for the rotor 1.

  Next, as a preferred example of the drive control method for the composite rotary electric machine according to the first to second inventions of the present invention described above, the coefficient obtained from the torque command values of the two rotors is set to a large torque ratio of each rotor. An example in which a finite value is set when the input of the torque command value of the rotor having a small torque is zero will be described.

  FIG. 7 is a view for explaining still another example of the preferred example of the drive control method for the composite rotating electrical machine of the present invention. FIG. 7 shows a look-up table for deriving the current multiplication factor η1 of the current command value of the rotor 1 when one rotor of the composite rotating electric machine is the rotor 1 and the other rotor is the rotor 2. . In the hatched portion, the motor torque characteristic is a non-linear region. Here, the case where the current multiplication factor η1 becomes very large is ignored, and the current multiplication factor η1 with respect to the current command value of the rotor 1 is set to a finite value. Due to this effect, the number of data in the lookup table can be reduced, so that the map data can be reduced and the required data storage area can also be reduced.

  Next, as a preferred example of the drive control method for the composite rotating electrical machine according to the first to third inventions of the present invention described above, the current command value that is the basis of each rotor of the composite rotating electrical machine is the DQ axis current amplitude and An example in which output is performed at the β angle will be described.

  FIG. 8 is a diagram for explaining still another example of the preferred example of the drive control method for the composite rotating electrical machine of the present invention. FIG. 8 shows a look-up table in which the current command value of either rotor of the composite rotating electrical machine is displayed by DQ axis current amplitude Idq and β angle. By outputting the current command value of each rotor of the composite rotating electric machine using the DQ axis amplitude and the β angle, adaptation to the current controller is facilitated.

  Next, as a preferred example of the composite rotary electric machine drive control method according to the first to third inventions of the present invention described above, the current command values as the basis of the respective rotors of the composite rotary electric machine are the D axis and Q axis. An example in which output is performed with current amplitude will be described.

  FIG. 9 is a diagram for explaining still another example of the preferred example of the drive control method for the composite rotating electrical machine of the present invention. FIG. 9 shows a look-up table in which the current command value of either rotor of the composite rotating electrical machine is displayed by the D-axis current amplitude Id and the Q-axis current amplitude Iq. By outputting the current command value of each rotor of the composite rotating electrical machine using the D-axis and Q-axis current amplitudes, adaptation to the current controller is facilitated.

  Next, as a preferred example of the drive control method for the composite rotating electrical machine according to the first to third aspects of the present invention described above, the current command value that is the basis of each rotor of the composite rotating electrical machine is approximated by a polynomial expression. An example of the configuration will be described. As shown in FIG. 9, by approximating the D-axis current amplitude Id and the Q-axis current amplitude Iq, the number of data in the look-up table can be greatly reduced. Therefore, the map data can be reduced, and the necessary data storage area is also provided. Can be reduced.

  Hereinafter, the relationship between the torque command value and the current multiplication factor in the various lookup tables described above will be described.

  FIG. 10 shows actual torque characteristics of each rotor of the rotating electrical machine using the composite magnetic flux. FIG. 11 shows the current multiplication coefficient η1 of the rotor 1 when the command torque value of each rotor is used as a parameter. In FIG. 10, since the torque characteristic is linear in the hatched region, the command torque value τ1_ope and the actual torque value τ1_act are substantially equal (τ1_act = τ1_ope), so the current multiplication factor η1 is ≈1. Further, the value of the current multiplication factor η1 corresponding to the command torque value τ1 of the rotor 1 in FIG. 11 corresponds to this.

  In addition, in the area outside hatching in FIG. 10, the torque characteristics are nonlinear, so the command torque value and the actual torque value do not match. (See FIG. 10. Points α, β, and γ) Here, when the torque value at the non-hatched region β in FIG. 10 is commanded, only the torque at the α point can actually be output due to the nonlinearity of the torque characteristics. (Τ_α <τ_β) Therefore, in order to realize the torque at the β point, it is necessary to give a torque command at the γ point. Here, when the current multiplication coefficient η1_β for realizing the torque at the β point is η1_β = τ1_γ / τ1_β, the command torque τ1_ope of the rotor 1 is derived by defining τ1_ope = η1_β × τ1_β (= τ1_γ). Can do. Therefore, the current multiplication coefficient η1 with respect to the command torque of the rotor 1 is 1 or more because of the relationship η1 = τ1_γ / τ1_β. The locus in which the current multiplication factor η1 with respect to the command torque value τ1 of the rotor 1 in FIG. 11 is 1 or more corresponds to this.

  The drive control method for a composite rotating electrical machine according to the present invention includes a rotor having a permanent magnet and a stator, and a current command for each rotor in the drive control method for the composite rotary electrical machine in which a composite current is supplied to the stator coil.
