An object is to obtain a rotating machine control device and an electric power steering control device that are capable of discharging a smoothing capacitor within a short time while preventing size increase of the entire device. A control unit 1 includes: control command generation means 16 for generating a first control command that specifies current to flow through a first winding set M1, and a second control command that specifies current to flow through a second winding set M2; voltage calculation means 6 for calculating a first voltage command from the first control command and calculating a second voltage command from the second control command; and first voltage application means 7a and second voltage application means 7b for applying voltages to the first winding set M1 and the second winding set M2 of a rotating machine 3 on the basis of the first voltage command and the second voltage command, wherein discharge control for electric charge of a smoothing capacitor 5 is performed while torque generated by current flowing from the smoothing capacitor 5 to the first winding set M1 and torque generated by current flowing from the capacitor to the second winding set M2 are cancelled out with each other.
