Adaptive power source control system

A method of controlling a power source associated with a machine, comprising:

• determining a cumulative torque demand based on signals received from an implement and a traction device, the implement and the traction device receiving power from the power source;
• determining that the torque demand exceeds a peak power source torque;
• determining, in response to determining that the torque demand exceeds the peak power source torque, a first difference between a first power source speed and an underspeed setpoint;
• determining a first torque distribution associated with the power source, the implement, and the traction device, wherein the first torque distribution is based on the first difference and respective torque priority values associated with the power source, the implement, and the traction device;
• modifying at least one of the torque priority values to generate a first modified torque priority value based on the first difference;
• and
• determining, in a closed-loop manner, at least one additional torque distribution,
• wherein the at least one additional torque distribution is based on the first modified torque priority value and a second power source speed different than the first power source speed, and
• wherein the at least one additional torque distribution limits a decrease in power source speed.

A machine, comprising:

• a power source;
• at least one parasitic load receiving power from the power source;
• a transmission coupled to the power source;
• and
• a control system in communication with the power source, the at least one parasitic load, and the transmission, wherein the control system is operable to determine a difference between an underspeed setpoint associated with a peak power source torque, and a first power source speed;
• determine a torque distribution associated with the power source and the at least one parasitic load, wherein the torque distribution is based on the difference and respective torque priority values associated with the power source and the at least one parasitic load;
• and
• modify at least one of the respective torque priority values, wherein modifying at least one of the torque priority values reduces a difference between the underspeed set point and a second power source speed different than the first power source speed.
