Abstract:
To provide an AC rotary machine control device which can superimpose the 5th order and the 7th order harmonic voltages on the AC voltage applied to the AC rotary machine by calculation processing of low processing load, and an electric power steering device provided with the same. An AC rotary machine control device performs middle voltage offset processing that adds offset value to middle voltage command when middle voltage command in three phase basic voltage commands is larger than vibration center voltage, and subtracts offset value from middle voltage command when middle voltage command is smaller than vibration center voltage.

Claim (Index 1):
An AC rotary machine control device comprising:\n an inverter that applies voltage to three phase windings which an AC rotary machine has, and a controller that controls the inverter, wherein m (m is a natural number) sets of the three phase windings and the inverters are provided for the one AC rotary machine, wherein the controller is provided with a voltage command calculator that, for each set of the m sets, calculates three phase voltage commands which are voltage commands to respective phases of the three phase windings; and an inverter controller that, for each set, controls on/off of a plurality of switching devices which the inverter has, based on a DC voltage supplied to the inverter and the three phase voltage commands, wherein the voltage command calculator is provided with a basic command calculator that, for each set, calculates three phase basic voltage commands which are basic values of the three phase voltage commands; and a voltage command correction calculator that calculates the final three phase voltage commands by correcting the three phase basic voltage commands, and wherein the voltage command correction calculator, for each set, determines a basic voltage command of a phase which becomes a middle voltage among the three phase basic voltage commands, as a middle voltage command; and performs middle voltage offset processing that adds an offset value, which is set to a positive value, to the middle voltage command, when the middle voltage command is larger than vibration center voltage, and subtracts the offset value from the middle voltage command, when the middle voltage command is smaller than the vibration center voltage.
