CONTROL SYSTEM FOR A DUAL REDUNDANT MOTOR/GENERATOR AND ENGINE

摘要

An exemplary electrical system may include a power plant operable to provide motive power, and a first and a second motor/generator operatively coupled to a common gear shaft, and to the power plant via a gearbox and drive shaft. The exemplary electrical system may further include a system controller configured to selectively operate at least one of the first motor/generator and the second motor/generator in one of a motor operating mode and a generator operating mode based on at least one parameter. The at least one parameter may be, but is not limited to, vibration and torque. In the motor operating mode, the first and/or second motor/generator provides power to the power plant. In the generator operating mode, the first and/or the second motor/generator extracts power from the power plant.
