Identification of Dynamic Systems
摘要
This chapter presents techniques for obtaining useful synthetic mathematical models of a dynamic system, based on the signals recorded during its practical operation. These signals may originate from transducer measurements of the system's dynamical evolution, including its input, output, or both. The synthesized models are categorized as either parametric or non-parametric. Non-parametric models rely on time or frequency functions that descriptively summarize the system's vibrational characteristics. In contrast, parametric models yield lumped parameter models that closely approximate the mathematical models described in the earlier chapters (Chapters 1 to 3) of this work.
