Abstract: There is described herein a real-time scheme, implementable in software, hardware, or a combination thereof, to detect a resonating frequency of a structure from a sensed signal and dynamically set the center frequency of an adaptive compensator for effective attenuation of the resonating frequency.

Abstract: There are described herein methods and systems for providing an engine computer with a power request having been determined by an aircraft computer. The power request is sent over a communication bus and once it reaches the engine computer, the latency due to the different update rates of the engine computer and the aircraft computer are compensated for.
