Let’s do system identification with SMIT!

SMIT (Structural Modal Identification Toolsuite) is an interactive program designed to perform system identification which constructs a numeric model using sensor data. SMIT is customized to identify building and bridge systems for the quality estimation of mode shapes; but it actually is applicable to a wide range of structures if the user focuses only on modal parameters. SMIT is developed in Matlab and can be downloaded for free.
