Summary
The proposed Jupiter Icy Moon Orbiter, JIMO, mission selected a Brayton power conversion system as its electrical power generator. Although the JIMO mission power conversion system was expected to produce in the order of 100 kW, an available 2 kW Brayton system was used to develop control system strategies for the JIMO mission. This report describes the shunt loading voltage/speed regulation control concept developed for the 2 kW system, and the transient performance of controls. The 2 kW alternator is a permanent magnet alternator as proposed for the JIMO mission, and operates at a similar speed and internal impedance, allowing it to be used as an accurate model for performance of the larger system. The JIMO mission was cancelled in September 2005.
