Abstract: A drive control system for an electric motor includes a slippage determination device, a tentative vibration damper torque calculator, a vibration damper torque limit value setting device, a vibration damper torque setting device, and a control device. The vibration damper torque setting device is configured to set a control torque obtained by limiting a tentative vibration damper torque using a limit value set by the vibration damper torque limit value setting device. The control device is configured to control driving of the electric motor in accordance with a command value of a torque obtained by combining a requested torque for the electric motor with the control torque set by the vibration damper torque setting device.

Abstract: A motor control apparatus drives an inverter which supplies and receives electric power with respect to a motor by pulse width modulation. The motor control apparatus sets a frequency of a carrier such that a frequency of a sideband wave component of the carrier which is used for the pulse width modulation and a frequency of a predetermined rotation order of the motor become different from each other.

Abstract: A load drive control system for a hybrid vehicle includes a zero current control execution device and an error compensating device. The zero current control execution device is configured to control a converter to output a substantially constant raised voltage that is higher than an inductive voltage generated in an electric motor. The error compensating device is configured to compensate for an attachment error of a first position detector based on a d-axis voltage command value for the electric motor calculated during zero current control.
