Abstract
A parameter concerning rotation of a motor is estimated (first estimation). A parameter concerning rotation of the motor is estimated, based on a model representing a prescribed change in a rotation speed of the motor (second estimation). It is determined whether an anomaly has occurred in the rotation of the motor, based on the parameter estimated in the first estimation and the parameter estimated in the second estimation.
Claims20
A motor control apparatus comprising:
- a first estimation unit configured to estimate a parameter concerning rotation of a motor;
- a second estimation unit configured to estimate a parameter concerning rotation of the motor, based on a model representing a prescribed change in a rotation speed of the motor;
- and
