A Method for Correcting a Damaged Tacho Signal
Original language description
Order analysis of vibration signals from rotary machinery typically uses tacho sensors utilizing either optical or magnetic principle for precise measurement of shaft angle position that can be calculated to the rotational speed. In some cases, the tacho signal can be distorted in numerous ways, for example, the presence of additional corrupting edges that show up as strong damage to the speed profile. This paper introduces an automatic algorithmic technique to remove corrupting edges from the tacho signal via a criterion-based approach called. The properties of the method are demonstrated on a~simple theoretical example as well as on a~real signal from a turbojet run-up that exhibits superior functionality even during rapid speed changes; such variations are typically problematic. The procedure also preserves a number of correct edges even when the corrupting edge is very close to the correct one.
