Creating and Manipulating Linear Models

Control System Toolbox lets you represent and manipulate linear models of dynamic systems as objects. All standard representations are supported, including transfer function, zero-pole-gain, explicit and descriptor state space, and frequency response data. Linear models can be SISO, MIMO, continuous, or discrete. In addition, you can accurately model and simulate systems with time delays, including feedback loops with delays.

Control System Toolbox provides commands for:

• Performing arithmetic on linear models
• Building complex block diagrams by connecting simple models in series, parallel, or feedback
• Discretizing continuous-time models
• Computing low-order approximations of high-order models

You can also use the LTI block to bring linear model objects into Simulink.

Building a linear model of your plant is usually the first step in designing a control system. If no plant model is available, you can build one by fitting test data using System Identification Toolbox, or by linearizing a Simulink model using Simulink Control Design (both available separately). Either model can be imported into Control System Toolbox as an object. Once you have created an object that represents your plant, you can use Control System Toolbox to analyze and control it.
