System Identification Toolbox provides several nonlinear black-box model structures, which have traditionally been useful for representing dynamic systems.
|Model Type||Usage||Learn More|
|Nonlinear ARX model|
|Use to represent nonlinear extensions of linear models. This structure allows you to model complex nonlinear behavior using flexible nonlinear functions, such as wavelet and sigmoid networks.||Identifying Nonlinear ARX Models|
|Linear models with input/output nonlinearities, or Hammerstein-Wiener
|Use to represent linear models with static nonlinearities.||Identifying Hammerstein-Wiener Models|
|Nonlinear grey-box model|
|Use to represent nonlinear ODEs with unknown parameters.||Estimating Nonlinear Grey-Box Models|
