  • Publication number: 20190229661
    Abstract: In a MG control device, a standard voltage calculation part calculates a d axis standard voltage and a q axis standard voltage in a standard state in which no demagnetization occurs in permanent magnets of a MG. A magnetic flux change amount estimation value calculation part calculates a basic magnetic flux change amount estimation value based on a deviation of a specific value from the q-axis standard voltage. This specific value is obtained by multiplying q axis real voltage with a ratio of the d axis standard voltage and the d axis real voltage. A magnetic flux change amount estimation value correction part adjusts a magnetic flux change amount estimation value by correcting the basic magnetic flux change amount estimation value relatively to a detection threshold value based on characteristic change of the MG in a demagnetization state of the permanent magnets of the MG.

  • Publication number: 20190229663
    Abstract: In a MG control device, a standard voltage calculation part calculates a d-axis standard voltage Vd_std and a q-axis standard voltage Vq_std to be supplied to a MG. A first magnetic flux change amount estimation value calculation part calculates a first magnetic flux change amount estimation value ??1 based on a deviation of a specific value from the q axis standard voltage Vq_std, where the specific value is obtained by multiplying a ratio (Vd_std/Vd_real) with a q-axis real voltage Vq_real, where Vd_real represents a d-axis real voltage. A second magnetic flux change amount estimation value calculation part calculates a second magnetic flux change amount estimation value ??2 based on a deviation of the q-axis real voltage Vq_real from the q-axis standard voltage Vq_std. The calculation switching part selects one of ??1 and ??2 based on an operation state of the MG.
