Abstract:
A control device for a plurality of rotating electrical machines, comprising:an inverter connected to the plurality of rotating electrical machines; a sensor for detecting a rotational angular velocity and a rotational phase of a rotor in each rotating electrical machine; and a motor controller configured to: determine a control current of each rotating electrical machine based on target torques of all of the plurality of rotating electrical machines and the rotational angular velocities of all of the plurality of rotating electrical machines; control the inverter to supply a composite current to all of the plurality of rotating electrical machines, the composite current being a combination of the control currents for each rotating electrical machine; and determine the control current of each rotating electrical machine so that an average current value of the composite current takes a minimum value, while maintaining the target torques of all of the plurality of rotating electrical machines.
