ROTARY ELECTRIC MACHINE CONTROL DEVICE

In a rotating electrical machine control device for controlling an AC voltage command output to a power converter for converting a DC voltage from a DC power source into an AC voltage and applying the AC voltage to a rotating electrical machine, the AC voltage command is generated such that a 1f component of a phase current follows a command current. However, when there is an error in rotor position information obtained on the basis of a position detector that detects the position of a rotor of a rotating electrical machine, an offset component is generated in a phase current. The offset compensation device is characterized by comprising an offset compensation part which calculates an offset compensation amount according to the detection result of the detection current so as to reduce the offset component of the detection current of the current detector, and the offset compensation instruction is added and subtracted to the AC voltage instruction output by the voltage instruction generation part. 在对输出到将直流电源的直
