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.
1. A method of controlling an APU system having a permanent magnet generator comprising the steps of:(1) determining a speed offset of an APU in response to an applied load to the permanent ma et alternator;(2) selecting the greater of the speed offset of said step (1) and an APU set point to obtain a resultant speed set point greater then 100% of a full speed; and(3) communicating the resultant speed set point to an APU fuel controller. 2. A method as recited in claim 1, wherein said step (1) further comprises:relating a voltage offset to a speed set po...
