Abstract
A rotating electrical machine control system includes a base current instruction setting part that sets a base current instruction based on target torque of a rotating electrical machine; a correction current instruction setting part that sets a correction current instruction with a frequency determined based on torque ripple; and a current control part that performs current feedback control to compute a voltage instruction which is an instruction value of a voltage to be applied to the rotating electrical machine. The current control part includes a first current control part whose control target is a component of the base current instruction; and a second current control part whose control target is a component of the correction current instruction. A gain of the second current control part is set to be low compared to a gain of the first current control part.
