Document Type and Number:
Japanese Patent JP7189075
Kind Code:
B2
Abstract:
To provide motor drive control arrangement, method and system capable of reducing current pulsation, when performing drive control of a motor by model prediction control.SOLUTION: A motor drive control arrangement for controlling a motor, being driven with the output from an inverter circuit, generates a plurality of voltage patterns that can be outputted from an inverter circuit, and smooths each of the plurality of time series voltage patterns as a time series smooth voltage pattern. For each of the plurality of time series smooth voltage patterns, the motor drive control arrangement predicts the value of a prescribed physical quantity related to control purpose of the motor when the time series smooth voltage pattern is inputted to the motor, as a prediction value, selects the time series smooth voltage pattern corresponding to the prediction value of highest evaluation, and controls the inverter circuit so as to output the selected time series smooth voltage pattern.SELECTED DRAWING: Figure 1
