We describe a method for controlling chaos-generated cyclic variations in a pulse combustor. The method is applied to a recently developed thermal pulse combustor model and utilizes a map-based, adaptive proportional feedback algorithm. With this technique we show that it is possible to greatly reduce cycle-by-cycle pulse variation. We further show that minimizing cyclic variation allows combustor operation at conditions well beyond the normal flameout limit.
