Abstract

Thermoacoustic instabilities in combustion processes involve pressure and velocity limit cycling oscillations that can have adverse effects on system performance. Using a nonlinear state space model for combustion processes that captures the coupling between unsteady combustion and acoustics, a direct adaptive control framework is used to design high-performance robust controllers for suppressing thermoacoustic oscillations in the face of system parametric uncertainty
