- Step 3 Based on the command speed pattern obtained in E102, the data acquisition speed section (see Table 2) and the magnetic pole estimation acquisition data (maximum command current, Set the average command current and instantaneous command current (E103, E104) 0
- Step 4 Calculate the speed deviation by subtracting the detected speed from the commanded speed (E106) o
- Step 5 Calculate the command torque (command current) by multiplying the speed deviation by the speed gain (one of speed proportional gain, speed proportional integral gain, and speed integral gain) (E107) 0
- Step 6 The mode section judgment means performs the judgment process of the mode section (first cycle section and second cycle section) from the commanded speed, and switches the mode from the first cycle section to the second cycle section according to the result. Performed by switch (E109).
- Steps 8A to 8C (E1101 to E1104) are performed in the first cycle section obtained in E109, and the step is performed in the second cycle section obtained in E107. Perform the operations from 9 A to Step 9 C (E 1201 to E 1205).
- Step 8 A Input the command torque (command current) calculated in Step 5 for the q-axis command current, and enter zero for the d-axis command current (E1101).
- Step 8 B Determine whether the commanded speed is in the data acquisition speed section, and calculate the first command current data (first command torque data) from the command torque in the determined section (E 1102, E 1 103).
- Step 8C The first command current data is stored in the memory by the first memory storage means (E1104).
- Step 9 A Input zero for the q-axis command current, and input the command torque (command current) calculated in step 5 for the d-axis command current (E 1201).
- Step 9B Determine whether the commanded speed is within the data acquisition speed section and calculate the second command current data (second command torque data) from the commanded torque in the determined section. (E1202, E1203).
- Step 9 C Store the second command current data in the memory by the second memory storage means (E 1204) o
- Step 11 The difference between the first command current data and the second command current data called at E110 is calculated as a data deviation (E110A).
- Step 12 Compare the data deviation with the data deviation limit level. If the result is “data deviation ⁇ data deviation limit level”, change the phase to a predetermined phase, and then The processing operation is performed again from (E110B, E110C).
- Step 12 A Compare the data deviation with the data deviation limit level. If the result is “data deviation ⁇ data deviation limit level”, the first command current data called in E 110 and the second command current data are compared. Using the command current data, the estimated initial magnetic pole position is calculated by the estimated initial magnetic pole calculation means using Eq. (8) (E111).
- the corrected initial magnetic pole position 0comp is calculated by adding the estimated initial magnetic pole position S est to the default initial magnetic pole position 00 by the corrected initial magnetic pole calculating means using the equation (9) (E112).
