Abstract
A rotating electrical machine control apparatus includes a position information generator and a controller, where a reset request is given from the controller, the position information generator stores position information in accordance with a first signal indicating the rotation position of a rotating electrical machine in a position storage portion, and thereafter updates the position information stored in the position storage portion on the basis of a second signal. The controller gives a reset request to the position information generator, and determines an abnormality of the position information on the basis of the position information obtained before and after the reset request is given.
Claims15
A rotating electrical machine control apparatus comprising:
- a position information generator that receives, as input, a first signal indicating a rotation position of a rotating electrical machine and a second signal indicating an amount of change of the rotation position, and generates position information indicating the rotation position based on the input signals;
- and
- a controller that controls the rotating electrical machine based on the position information output from the position information generator,
- wherein the position information generator includes
- a position storage portion that stores the position information,
- an updating portion that repeatedly updates the position information stored in the position storage portion based on the second signal,
- a setting portion that sets, in a case where a reset request is given from the controller, the position information stored in the position storage portion to position information in accordance with the first signal, and
- an output portion that outputs the position information stored in the position storage portion to the controller, and
- wherein the controller includes
- an obtaining portion that obtains the position information output from the position information generator, and
- an abnormality determination portion that gives the reset request to the position information generator, and determines an abnormality of the position information based on the position information obtained by the obtaining portion before and after the reset request is given.
A rotating electrical machine control apparatus comprising:
- position information generating means for receiving, as input, a first signal indicating a rotation position of a rotating electrical machine and a second signal indicating an amount of change of the rotation position, and generating position information indicating the rotation position based on the input signals;
- and
- control means for controlling the rotating electrical machine based on the position information output from the position information generating means,
- wherein the position information generating means includes
- position storage means for storing the position information,
- updating means for repeatedly updating the position information stored in the position storage means based on the second signal,
- setting means for setting, in a case where a reset request is given from the control means, the position information stored in the position storage means to position information in accordance with the first signal, and
- output means for outputting the position information stored in the position storage means to the control means, and
- wherein the control means includes
- obtaining means for obtaining the position information output from the position information generating means, and
- abnormality determination means for giving the reset request to the position information generating means, and determining an abnormality of the position information based on the position information obtained by the obtaining means before and after the reset request is given.
