At the aim of enhancing Signal to Noise Ratio (SNR) of measured response data to acquire more reliable parameter identification results, Incremental Harmonic Balance Method (IHBM) is introduced into the identification algorithm construction.This algorithm mainly consists of two functions.The one is the identification of system parameters including governing coefficients and time delays using classic Newton-Raphson process, the other is the rectification of noise-polluted response using IHB method.
