Abstract :
Natural frequency extraction in the frequency domain using measured frequency responses is an ill-conditioned problem. A method is proposed to improve the accuracy of the previously extracted natural frequencies. It is shown from results that the method can improve the accuracy of the natural frequencies extracted from synthetic and measured frequency response samples
