Abstract: Detrimental combustion instability is unwanted in gas turbines, aeroengines, rocket motors, and many other combustion systems. In this work, we design and implement a sliding mode controller (SMC) to mitigate self-sustained combustion oscillations in an open-ended thermoacoustic system. An acoustically compact heat source is confined and modeled by using a modified form of King's Law. Coupling the heat source model with a Galerkin series expansion of flow disturbances provides a platform to conduct pseudospect…
