Abstract

The low computation cost, short delay and accuracy of SINTRACK, makes it a very interesting real-time signal processing tool for detection and estimation of damped sinusoids in noise. A noise analysis, as well as a parameters´ optimal adjustment analysis are provided. SINTRACK is successfully applied for detection and estimation of a HALE wing bending and torsion oscillations, validating a theoretical flutter prediction law
