Abstract

This paper presents the concept and design of a two-layer robust control system for suppression of combustion instabilities over a wide range of operation. The control law is synthesized based on a multiple-time-scale model of combustion dynamics. Control actions on the fast-time scale are provided by secondary fuel injection, and are gain-scheduled according to the variations of mean-flow temperature and velocity on the slow-time scale. A linear parameter varying (LPV) L₂-gain control law is formulated in the setting of differential game theory. Simulation experiments have been conducted to evaluate the control law under wide-range operation of a generic combustor in terms of the trade-off among: (1) fuel injection rate and pressure oscillation; (2) transient and steady responses; and (3) stability robustness and performance.
