摘要：

This paper addresses the experimental investigation of a combustion system using a backward step configuration, with the goal of understanding combustion instability and its control. In order to carry out a systematic study of the various subcomponents of the combustion dynamics including hydrodynamics and heat-release, various sensors and actuators have been included in this setup that provide new insight into the underlying mechanisms, which are discussed in this paper. A preliminary model using Proper Orthogonal Decomposition (POD) and a model-based controller using the adaptive posi-cast strategy are presented. The model and the control design are verified using an air-flow injector in the step combustor at Re=6300 and an equivalence ratio of 0.85 and are shown to result in a 7.5dB pressure reduction.
