Recovering speed in driveline assembly

A program product stored on a computer readable storage medium, the program product operative to recover speed in a driveline assembly when executed, the computer readable storage medium comprising program code for:

• comparing a shaft speed of a rotatable shaft of the driveline assembly with a minimum speed threshold, wherein the rotatable shaft mechanically couples a load to a gas turbine and a motor, the gas turbine delivering a first power output to the load and the motor delivering a second power output to the load less than the first power output;
• and
• increasing a set point of the motor based on an operating characteristic of the driveline assembly in response to the shaft speed being less than the minimum speed threshold, wherein the operating characteristic of the driveline assembly includes one of a fuel intake of the gas turbine, an exhaust temperature of the gas turbine, and a deceleration of the rotatable shaft.

An apparatus comprising:

• a motor coupled to a torque converter, wherein the torque converter couples the motor to a load and a gas turbine through a rotatable shaft within a driveline assembly, and multiplies a power output of the motor to the rotatable shaft by a conversion factor;
• and
• a controller component of the motor in communication with the torque converter, wherein the controller component increases the conversion factor of the torque converter based on an operating characteristic of the driveline assembly in response to a shaft speed of the rotatable shaft being less than a minimum speed threshold, wherein the operating characteristic of the driveline assembly includes one of a fuel intake of the gas turbine, an exhaust temperature of the gas turbine, and a deceleration of the rotatable shaft.
