A temperature estimation module {104} estimates a change in temperature of the magnets associated with the rotor of the motor (117) based on an operational magnetic flux strength that is compared to a reference magnetic flux strength determined at a known- ambient temperature and for a predetermined operating range of the motor. The temperature estimation module (104) or the system (120) establishes a relationship between the estimated change in the temperature and a magnetic torque component of a target output torque of the motor (117) consistent with the predetermined operating range. The current adjustment module (107) or the system (120) adjusts a command (e.g., quadrature-axis current command) for the motor (117) to compensate for shaft torque variation associated with the estimated change in the temperature In conformance with the established relationship. |
