An auxiliary power unit (APU) control system 18 for an aircraft 20 is disclosed, and includes an APU 22 drivingly coupled to one or more generators 24, one or more processors, and a memory coupled to the one or more processors. The memory stores data comprising a database and program code that, when executed by the one or more processors, causes the APU control system to receive one or more ambient signals indicative of an air density value and one or more power signals indicative of a specific amount of power generated by the APU. The system is further configured to determine a first variable rotational speed of the APU based on the air density value, to continue generating the specific amount of power. After instructing the APU to operate at the first variable rotational speed, the system is further configured to determine a second variable rotational speed of the APU, based on a received electrical load signal of the generator(s).
