Manage data and model objects available in the System Identification Toolbox™. System identification is about building models from data. A data set is characterized by several pieces of
Obtain linear approximations of a complex, nonlinear system by means of linear model identification. The approach is based on selection of an input signal that excites the system. A linear
The benefits of regularization for identification of linear and nonlinear models.
Estimate models using frequency domain data. The estimation and validation of models using frequency domain data work the same way as they do with time domain data. This provides a great
