A system and method are provided for controlling an electric motor driven lubrication supply pump that is supplied with electrical power from a power bus, and that supplies lubricant to a rotating machine that is at least part of a vehicle subsystem. A determination is made that the subsystem is being started-up. Moreover, one or more lubricant parameters, power bus electrical state, and one or more lubricant load states are determined. The electrical power supplied from the power bus to the electric motor is varied, based on the one or more lubricant parameters, the power bus electrical state, and the one or more lubricant load states.

1. An aircraft lubrication supply system, comprising: a motor adapted to receive electrical power from a power bus and operable, upon receipt of the electrical power, to rotate and supply a drive torque;a pump coupled to receive the drive torque from the motor and configured, in response thereto, to supply lubricant to a rotating machine; anda controller configured to couple to the power bus, the controller further adapted to receive signals representative of lubricant supply temperature, lubricant return temperature, lubricant supply pressure, pump speed, rotating machine rotational speed, electrical power needed by other electric loads on the power bus, electrical power being supplied from the power bus to other electrical loads, and a system startup signal indicating that at least the lubrication supply system is being started up, the controller responsive to at least these signals to: (i) determine, in real-time, and based on at least these signals, a minimal amount of electrical power that may be supplied from the power bus to the motor, and(ii) implement startup control logic to to only selectively energize the motor from the power bus to the minimal amount. 2. The system of claim 1, wherein the controller is further operable to determine when the startup control logic should no longer be implemented and, upon making this determination, implements operational control logic. 3. The system of claim 1, further comprising: a fuel pump in fluid communication with, and operable to supply fuel to, the rotating machine,wherein the controller additionally receives a signal representative of fuel pump speed.
