Estimate the parameters of an ARX or AR model. Syntax. m = arx ... See Multivariable ARX Models: The idarx Model in the Tutorial for exact definitions.

However, the ARX model captures some of the stochastic dynamics as part of the system dynamics. In this model, the transfer function of the deterministic part G ...

ARX Model. An autoregressive exogenous input (ARX) model is a combination of an AR model and an X model, and it is represented by the following equation: y(t)=c+a1y(t−1)+a2y(t−2)+… +apy(t−p+b1u(t−1)+b2u(t−2)+… +bqu(t−q)+e(t)

arx performs the estimation using a least-squares method and the polynomial orders specified in [na nb nk] . The model properties include covariances (parameter ...
