摘要:
Provided is a control device for a permanent magnet-type rotating electrical machine (100), which includes a current coordinate transformation unit (109) configured to output a d-axis current and a q-axis current by coordinate transformation of three-phase AC currents respectively detected by current detection units (111, 112, 113), a current correction direction calculation unit (108) configured to calculate a current correction direction through use of the d-axis current and the q-axis current, and a current correction amount addition unit (102) configured to correct a d-axis current command and a q-axis current command based on the current correction direction. In this manner, an induced voltage is converged to lie within a maximum voltage circle in accordance with a power supply voltage.
