| Abstract: | The extraction methods of free structural modal parameters from constrained test, which is the subproblem of the test boundary, transformation, are summarized and reviewed in this paper. The strengths, weaknesses and applicability of these methods are discussed respectively. Some problems still exiting in the theory and application are presented. Some future research trends on these methods are outlined. |
