摘要：

A novel derivation of a least-squares lattice filter is presented and applied to the identification of flexible structures. The vector-channel lattice given, derived in an infinite-dimensional history space, without matrix manipulations or geometric arguments, can constrain the autoregressive (AR) coefficients for several outputs to be the same. Numerical results for a simulated flexible structure compare the vector-channel lattice to the standard lattice filter. These results show that the frequencies and damping ratios for the most significant modes can be identified adaptively with lattice filters.
