✦ Synopsis
A Unified Matrix Polynomial Approach (UMPA) is discussed in this paper as a possible method of condensing multiple sets of Perturbed Boundary Condition (PBC) test data into a single modal model of the unmodified system. The PBC testing provides a much larger database that contains more information about the system when compared to a standard modal testing procedure. A 3 dof lumped mass system is used as a theoretical example to illustrate the procedure. Zero mean random noise is used to examine the alogrithm under the influence of noise.
