Title:
PARAMETER SETTING DEVICE FOR SETTING PARAMETER OF ELECTRIC MOTOR MODEL
Document Type and Number:
WIPO Patent Application WO/2022/085543
Kind Code:
A1
Abstract:
In the present invention, an electric motor model comprises: a model of a coil of a stator; and a model of a temperature detector for detecting the temperature of the coil. A parameter such as a thermal capacity is included in the electric motor model. Provided is a parameter setting unit comprising a parameter calculation unit that calculates a parameter so that a change in the temperature of the model of the temperature detector corresponds to a change in the actual temperature. The parameter calculation unit includes an evaluation unit that evaluates the temperature of the model of the temperature detector, the temperature having been calculated using the temporarily set parameter. The evaluation unit evaluates the temperature of the model of the temperature detector without evaluating any variables besides the temperature of the model of the temperature detector.
