Tracking Filter Design for Predictive Maintenance of Jet Engine - Different Approaches and Their Comparison

Abstract

The aim of this paper is to design, implement, test and compare several tracking filtration methods for predictive maintenance of a jet engine. Based on literature review multiple possible methods are described. Appropriate ones selected for further implementation are peak filtration, coherent demodulation, Vold-Kalman filtration and order analysis. Methods are tested to meet criteria set by an aircraft manufacturer and compared using simulated signals.The aim of this paper is to design, implement, test and compare several tracking filtration methods for predictive maintenance of a jet engine.
