This paper describes the application of active, open loop, control in effective damping of
severe combustion instabilities in a high pressure (ie, around 520 psi) gas turbine …

This paper describes a study of open loop control of combustion instability employing
harmonic fuel injection rate modulation at a non-resonant frequency. It's shown that this …

The results of a study of closed-loop active control of combustion instabilities using
subharmonic secondary fuel injection are presented. The tests were conducted in a …

This paper describes an experimental investigation of the performance of the adaptive
