Title:
CONTROL DEVICE FOR ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/216604
Kind Code:
A1
Abstract:
A control device (60) is provided with: field control units (80-82) that control a field current flowing through a field winding (32) to a field command current; first control units (90-92) that, when the modulation rate is greater than 1, control currents flowing through stator windings (34U-34W, 34UA-34WB) on the basis of a command value for controlling a main control amount to a command control amount; and second control units (70-75) that, when the modulation rate is smaller than a modulation rate for control by the first control units, control currents flowing through the stator windings by sinewave PWM control on the basis of the command value for controlling the main control amount to the command control amount. For example, before and after switching from control by the first control units to control by the second control units, the control device causes the field control units to perform control while making the command value that is used by the field control units continuous, and adjusts the command value that is used by either the first control units or the second control units. Accordingly, change of the main control amount with respect to the command control amount is suppressed.
