The conjugate gradient method, i.e., the iterative regularization method, is used in an inverse non-linear force vibration problem of estimating the unknown time-dependent external forces in a damped system with the displacement-dependent spring constant and damping coe$cients. The accuracy of the i
This paper is the third in the series on this topic. In the earlier papers, the dynamics of the steelpan notes were developed as systems of non-linear mode-localized oscillators which can show note-note and note-skirt coupling. The tonal qualities of a note depend on the coupling parameters and damp
An inverse non-linear force vibration problem based on the iterative regularization method, i.e., the conjugate gradient method (CGM), is used to estimate the unknown time-dependent external forces in a damped system having time-dependent system parameters by using the measured system displacement.
