System Identification Toolbox系统辨识工具箱入门手册

System identification is a methodology for building mathematical models of dynamic systems on page 1-4 using measurements of the system’s input and output signals. The process of system identification requires that you: • Measure the input and output signals on page 1-7 from your system in time or frequency domain. • Select a model structure on page 1-9. • Apply an estimation method on page 1-10 to estimate value for the adjustable parameters in the candidate model structure. • Evaluate the estimated model on page 1-16 to see if the model is adequate for your application needs.
