Abstract
An electric motor control device that performs a voltage phase control includes a voltage generator configured to calculate a d-q axis voltage command value, a stabilization filter having first to fourth filters determined based on a transfer characteristic from an applied voltage to an output electric current and configured to remove resonance characteristics in the d-q axis electric current, and a voltage application unit configured to apply an AC voltage to the electric motor based on the final d-q-axis voltage command value. The stabilization filter is configured to generate the final d-axis voltage command value based on a result obtained by using the first and second filters for each of the d-axis and the q-axis voltage command values and generate the final q-axis voltage command value based on a result obtained by using the third and fourth filters for each of the d-axis and the q-axis voltage command values.
