How does system identification work?
System identification uses the input and output signals you measure from a system to estimate the values of adjustable parameters in a given model structure. You can build models using time-domain input-output signals, frequency response data, time -series signals, and time-series spectra.
Why do we do system identification?
System Identification allows you to build mathematical models of a dynamic system based on measured data. 2. How is that done? Essentially by adjusting parameters within a given model until its out- put coincides as well as possible with the measured output.
What are the key steps to follow in system identification?
The steps involved in system identifica- tion are data acquisition, determination of a model structure, parameter estimation and model validation as shown in Figure 1. ...
