Abstract

A control system and method measures vibrations during operation of an engine connected with rotating accessories. A high vibration condition is identified responsive to a vibration amplitude exceeding a threshold and a vibration frequency being in a frequency band extending around an operating frequency of one rotating accessory. The system and method decide whether operating frequencies of the rotating accessories are within a crosstalk band from each other and, if so, the system and method shift the operating frequency of another rotating accessory to determine which rotating accessory is causing the vibrations.
