Transforming Between Linear Model Representations
Converting between state-space, polynomial, and frequency-response representations.
Reducing Model Order Using Pole-Zero Plots
You can use pole-zero plots of linear identified models to evaluate whether it might be useful to reduce model order. When confidence intervals for a pole-zero pair overlap, this overlap indicates a possible pole-zero cancellation.
Create and Plot Identified Models Using Control System Toolbox Software
Identify models and use the Linear System Analyzer to plot the models.

Using Identified Models for Control Design Applications
Using System Identification Toolbox™ models with Control System Toolbox™ software.
Subreferencing Models
Creating models with subsets of inputs and outputs from multivariable models at the command line.
状態空間実現
モード正準形式、コンパニオン正準形式、可観測正準形式、可制御正準形式の状態空間モデル。
Concatenating Models
Horizontal and vertical concatenation of model objects at the command line.
Merging Models
How to merge models to obtain a single model with parameters that are statistically weighed means of the parameters of the individual models.
Treating Noise Channels as Measured Inputs
Convert noise channels to measured channels and include the variance of the innovations.
