Modeling and Active Control of Thermoacoustic Instabilities
نویسندگان
چکیده
Due to stringent emission regulations, modern gas turbines work in lean premixed mode and thermoacoustic instabilities are often observed. They cause mechanical damage and therefore have to be reduced. This paper describes the development of an acoustic network model for a lab-scale lean premixed methane combustor at ETH Zurich. The model is verified against experimental data and is then used to develop an H∞-controller, with special concern given to fundamental limits imposed by the system. The proposed controller is then verified in simulations. Copyright 2005 IFAC

متن کاملThermoacoustic Instabilities: Modelling and Control
The goal of this study was twofold. First, modelling strategies were proposed to characterize the dynamics driving the thermoacoustic instabilities in a swirl-stabilized premixed burner. Secondly, this model was used to synthesize controllers in order to apply active control strategies to suppress this phenomenon. An experimental combustor model based on acoustic properties of the combustion ch...
متن کاملActive Control of Thermoacoustic Instability Using a Model-based Approach
Recently, active control has been pursued vigorously for combating thermoacoustic instabilities in the combustion process. While many of the reported experiments, with controllers that include filter components determined by trial and error, have demonstrated that the dominant thermoacoustic instability can be suppressed, often the response contains secondary peaks at other frequencies which we...
متن کاملScanned-Wavelength Temperature Sensors for Combustion Instabilities
Motivation Fuel lean combustion is often employed to reduce pollutant emissions (CO, NOx,...) and increase gas turbine lifetime via reduced temperature. However, lean combustion is susceptible to thermoacoustic instabilities and lean blowout (LBO). Thermoacoustic instabilities are due to the coupling of heat release to acoustic oscillations, and lead to reduced combustion efficiency and increas...
متن کاملA Model-Based Self-Tuning Controller for Thermoacoustic Instability
Active control of thermoacoustic instabilities in continuous premixed combustion processes is being increasingly investigated for operating at lean low NOX conditions. Recently, we have developed a model-based approach for active control design which accounts for the underlying acoustics, heat release dynamics, and sensor and actuator dynamics. While this model captures a number of the dominant...
