Non-linear system identification and fault diagnosis using a new GUI interpretation tool

There are two major contributions which are described in this paper. Firstly, a new graphical user interfaces (GUI) interpretation tool for the non-linear frequency response functions (FRF) is proposed. The tool is developed by pv-wave package to provide better ways and user friendly of displaying, interpreting and analysing of non-linear systems with significant non-linear effects. Secondly, the application of this identification tool for fault detection, identifying in the civil engineering.
