Updating quadratic palindromic models with no spillover effect on unmeasured spectral data

This work provides a solution to a specific technical problem in structural dynamics and control for engineers working with palindromic systems, but it is an incremental extension of existing no-spillover model updating techniques.

The paper addresses the model updating problem for quadratic palindromic systems, ensuring that the updated model matches measured spectral data while preserving the unmeasured spectral data exactly (no spillover). The authors develop a method to achieve this using the receptance method and provide a numerical example to demonstrate its effectiveness.
