1. A method of regulating operation of a machine comprising:

  • calculating a total power requirement of the machine based upon inputs;

    dividing the total power requirement between a first powertrain and a second powertrain to determine a first request signal and a second request signal;

    converting the first request signal to a first torque signal and converting the second request signal to a second torque signal;

    using the first torque signal to determine a direction of energy flow between a first energy storage device electrically coupled to a first motor-generator of the first powertrain; and

    using the second torque signal to determine a direction of energy flow between a second energy storage device electrically coupled to a second motor-generator of the second powertrain.
