Abstract: Methods and systems for detecting an oscillatory event are provided. According to one embodiment, a system may include a controller configured to provide a command signal to a positioning device and a processor communicatively coupled to the controller. The command signal may include a reference position. The processor may be configured to monitor a feedback signal responsive to the command signal. The feedback signal may include an actual position of the positioning device. The processor may be further configured to determine that within a predetermined period of time the actual position is both above a predetermined upper threshold and below a predetermined lower threshold. Based on the determination, the processor may declare the oscillatory event.

Abstract: Systems and methods for frequency separation in a gas turbine engine are provided herein. The systems and methods for frequency separation in a gas turbine engine may include determining a hot gas path natural frequency, determining a combustion dynamic frequency, and modifying a compressor discharge temperature to separate the combustion dynamic frequency from the hot gas path natural frequency. Specifically, the compressor discharge temperature may be modified by adjusting the inlet guide vanes of the compressor or by adjusting a temperature of air entering the compressor.

Abstract: Methods and systems for detecting an oscillation error are provided. According to one embodiment, a system may include a controller, and a processor communicatively coupled to the controller. The processor may be configured to detect an oscillatory event and increment a delay timer based on a duration of the oscillatory event. The delay timer may be set to a predetermined delay value. Additionally, the processor may be configured to determine that the delay timer exceeds the predetermined delay value and, based on the determination, declare the oscillation error.
