Abstract
An APU system provides an APU which drives a permanent magnet generator, an APU controller and a fuel controller. The APU controller controls the APU speed through communication with the fuel controller to maintain the generator voltage output within specified limits in response to an engine speed set point signal, a voltage set point signal and a voltage output signal.
