This paper presents the use of least square lattice filters in identification of the dynamics of highly flexible structures. Lattice filters have been used extensively in the areas of adaptive signal processing and speech synthesis. Herein, they are used for on-line identification of the number of modes, mode shapes and modal amplitude time series from the measurement data of flexible structures. The theory is illustrated using experimental data for a simple free-free beam and a more complex flexible, two-dimensional grid apparatus. Results presented indicate that the lattice filter approach produces effective identification of structural dynamics for the class of structures studied to this time.
