Applicability of selected indicators and algorithms for decision-making in an autonomous modal parameter estimation procedure

摘要

Recently, an increasing interest in formulation of autonomous modal estimation procedures has appeared inrnthe modal analysis users community. Unavoidability of the decision-making during modal parameterrnestimation constitutes a very important problem in automation of this procedure mainly due to limitedrnobjectivity of the decision-making. The authors concern 3 decision-making stages of the estimationrnprocedure: formulation of the analysis plan, stabilization diagram processing and model consolidation. In thernpaper some algorithms of decision-making aiding are proposed and their performance is presented forrnselected example of modal testing results. The proposed algorithms take advantage of both the deterministicrnand fuzzy type of reasoning. The idea of the algorithms is to act as the experienced analyst. Interactive use ofrnthe procedures is advised but automatic run is also possible. The formulated procedures proved to havernpromising performance but they still require comprehensive validation with use of various experimental data.
