Research on the Sensitivity Damage Identification Method Based on Closed-Loop Feedback Control

Abstract:

The structural mode parameters are identified by dynamic test technology, the system mode sensitivity(the structure parameter changes with characteristic parameter) is defined. At the same time, the controlled target is constructed according to feekback way, then the damage identification sensitivity is improved by feekbace force and its place. Finally, a simulant example is given to show the effective aspects of the method.
