Order tracking analysis by Maximum Likelihood Estimator This repository includes Matlab code for the Order Tracking Analysis of vibration/acoustic signals with multiple close/crossing using three methods:
(●) Our developed Maximum Likelihood Estimator method
(●) Time Variant Discrete Fourier Transform method of Blough
(●) Vold-Kalman Order Tracking method of Vold

testOTA_Sig1.m: this code applies OTA for simulated data or data obtained from simulation of constant-amp orders
testOTA_Sig2.m:this code applies OTA for simulated data or data obtained from simulation of 2-DOF system
testOTA_Sig3.m: this code applies OTA for simulated data obtained from numerical simulation of a rectangular SSSS plate using Matlab code inside /Plate
testOTA_Sig4.m: this code applies OTA for actual vibration data obtained from experimental results, vibration data is located in /otaP/input/plateViv.txt
