RESONANCE PREVENTION USING COMBUSTOR DAMPING RATES

Abstract:

Methods and systems for resonance suppression, can involve measuring signals with one or more sensors, wherein the signals are produced by a combustor associated with an actuator, and receiving at a controller the signals measured by the sensor or sensors. The controller can calculate a damping rate of the combustor. Based on the damping rate, the controller can modulate the actuator if the damping rate falls below a predefined threshold and can continue to modulate the actuator until the damping rate is adjusted and the resonance is suppressed. The sensor can be an acoustic sensor, an optical sensor, or another type of sensor.
