Abstract: A driving device for driving a first motor to transmit a driving force to a driven object and a second motor to transmit a driving force to the driven object include a controller and a corrector. The controller outputs a first voltage command value to drive the first motor and a second voltage command value to drive the second motor. The corrector corrects the first voltage command value and the second voltage command value, based on a parameter relating to driving of the first motor and the second motor obtained when an output torque of the first motor and an output torque of the second motor are applied to the driven object in opposite directions.

Abstract: A power supply system includes a first controller that, controls an MG1 inverter, a second controller that controls an MG2 inverter, and a voltage sensor that detects a voltage generated from a pair of output terminals. The first controller controls the MG1 inverter according to a target value of the voltage generated from the output terminals, irrespective of the magnitude of a deviation between the target value of the voltage generated from the output terminals, and the detected voltage. The second controller controls the MG2 inverter according to the deviation. This processing is implemented by an effective value computing unit, effective value PI control unit, and a neutral point output voltage command unit.

Abstract: An exemplary system includes a first electric motor and a second electric motor, which are coupled mechanically to one another via a common string of the system. The string has a torsional natural oscillation at a natural frequency. A first oscillating torque acts on the string by the first electric motor and a second oscillating torque acts on the string by the second electric motor. The second electric motor is arranged with respect to the first electric motor such that the effect of the second oscillating torque on the string results in damping of the excitation of the natural oscillation owing to the first oscillating torque.
