The present paper describes an active control system consisting of a fast-acting actuator
valve, coupled with a control algorithm capable of adaptive phase and amplitude control for …

Active control of pressure oscillations has been successfully applied to a lean premixed
prevapourised (LPP) combustion rig operating at atmospheric conditions. The design of the …

Active control of pressure oscillations has been successfully applied to a lean premixed

In the present work, an atmospheric pressure combustor using a modern aviation gas
turbine fuel nozzle was used to demonstrate active combustion control. The combustor …

This paper describes an experimental study of active control of combustion instabilities in a
gas turbine combustor simulator that burned natural gas premixed with preheated air under …

A dual-loop feedback control system was devised to suppress bimodal instabilities in a
dump combustor. Two types of instabilities were tested: one involving two anharmonic …

Emphasis on reducing the levels of pollutants created by gas turbine combustors has led to
the development of lean, premixed combustor designs, especially for industrial applications …

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 …
