Field predicting device for rotary electric machine, learning method of prediction model and rotary electric machine control system

摘要

Problem to be solved: to provide a field predicting apparatus for predicting the amount of field formed inside a rotary electric machine by a prediction model.The field predicting apparatus of the rotary electric machine predicts the amount of the field in the rotating electric machine provided with a stator for generating a rotating magnetic field when the three-phase alternating current flows and a rotor rotated by the rotating magnetic field.The field prediction apparatus has an d axis current of a rotating electric machine When a q-axis current and a mechanical angle or input data generated based on these parameters are input, a prediction model 62 is provided which outputs output data including a prediction amount of the vector potential in the rotating electric machine based on the neural network.The prediction model 62 comprises a prediction decoder 622 constructed based on the first learning decoder 652 of the auto encoder 65 and a predictive encoder 621 constructed on the basis of the second learning encoder 661.Diagram
