An electrified vehicle system includes an electric motor coupled to a drive wheel via a plurality of power transmission components and a control device. The control device is configured to act as: a feedforward control section configured based on a transfer function simulating vibration transmission characteristics of a power transmission system, receiving as an input a required torque of the electric motor from a driver, and outputting a base command torque of the electric motor; a timing estimation section estimating, based on information on the power transmission system, a timing at which a backlash between the plurality of power transmission components is eliminated; and a torque correction section applying, to the base command torque, a correction torque for reducing a vibration generated in the power transmission system due to elimination of the backlash, in response to an arrival of the timing estimated by the timing estimation section.

An electrical power supply system for a tethered small unmanned aerial vehicle has a ground station (1) connected to a universal aerial power supply (13) by a tether (10). The universal aerial power supply is capable of installation into the battery dock of a conventional free flying small unmanned aerial vehicle to deliver power to the small unmanned aerial vehicle systems during flight. The universal aerial power supply is compatible with a range of different small unmanned aerial vehicles and a range of classes of small unmanned aerial vehicles.

Systems and methods are disclosed for wireless powering and control of conveyors on shuttles. An example system may include a track, and a shuttle configured to move along the track, the shuttle having a conveyor, and a first induction coil. The system may include a second induction coil disposed at a first location along the track, where the second induction coil is configured to interact with the first induction coil to power the conveyor. The shuttle may not have an onboard power source coupled to the conveyor.
