Adaptive Combustion Instability Control with Saturation
The control of a class of combustion systems, suceptible to damage from self-excited combustion oscillations, is considered. An adaptive stable controller, called Self-Tuning Regulator (STR), has recently been developed, which meets the apparently contradictory challenge of relying as little as possible on a particular combustion model while providing some guarantee that the controller will cau...
متن کاملModeling and Control of Combustion Instability Using Fuel Injection
Active control using periodic fuel injection has the potential of suppressing combustion instability without radically changing the engine design or sacrificing performance. In this paper, we carry out a study of optimal model-based control of combustion instability using fuel injection. The model developed is physically based and includes the acoustics, the heat-release dynamics, their couplin...
متن کاملApplication of neural dynamic optimization to combustion-instability control
The suppression of thermoacoustic combustion instabilities represents one of the main goals in the design of reliable high-performances combustion chambers. Unstable dynamics arise when a non-linear coupling is established between the acoustic field and the flame front generating high-amplitude and low-frequency pressure and heat release oscillations, associated with the excitation of the combu...
متن کاملAn adaptive algorithm for control of combustion instability
We propose an adaptive algorithm for control of combustion instability suitable for reduction of acoustic pressure oscillations in gas turbine engines, and main burners and augmentors of jet engines over a large range of operating conditions, and supply an experimental demonstration of oscillation attenuation, the first for a large industrial-scale gas turbine combustor. The algorithm consists ...
متن کاملActive Control of Combustion Instability: Theory and Practice
One of the most successful applications of control technology in fluid systems is in the context of dynamic instability in continuous combustion systems. Recent results in this area have shown unequivocally that active control is not only a feasible technology for reducing the unsteady pressure oscillations, but also that the approach can be scaled up to large-scale industrial rigs. Models of c...
