Abstract :
The authors present adaptive parameter identification results for a complex flexible structure with many closely packed natural frequencies. Least-squares lattice filters are used to estimate the number of excited modes, natural frequencies and damping ratios from input/output data. One-step-ahead output prediction also is generated by the lattice filters
