<P>PROBLEM TO BE SOLVED: To provide a rotating electrical machine control system that effectively prevents the occurrence of an overcurrent and an overvoltage even if an error is superimposed in a current value detected by a current sensor. <P>SOLUTION: A rotating electrical machine control system 10 comprises: a motor generator MG2 as a rotating electrical machine; a DC/DC converter 14 including a reactor 20; smoothing capacitors C1, C2 connected to the DC/DC converter 14; and a control section 18 for controlling an inverter 16 in a PWM control mode using current feedback on a preset PWM condition. The control section 18 has a gain decision section 30 as a gain reduction section for reducing a feedback gain for the current feedback of the PWM control below a normally used normal gain when the frequency of power fluctuations of the motor generator MG2 matches a frequency in a resonance frequency range of an LC resonance circuit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
