© 1999 A P Dawling. Published by the American Institute of Aeronautics and Astronautics, Inc. Early work on active control of combustion oscillations is reviewed. It is over ten years since the first full-scale demonstration of the feasibility of feedback control to eliminate combustion instability. However, practical implementation requires controllers that have guaranteed performance across a range of combustor operating conditions. The development of such controllers needs the integration of ideas from acoustics, fluid mechanics, combustion, control and system identification. A nonlinear model of a ducted flame is used to analyse control strategies to stabilise self-excited oscillations. Recent work on both robust and adaptive controllers is discussed, with particular emphasis on controllers that continue to operate effectively as the flow conditions change.
