Creating and Manipulating Models

Creating LTI Models

The functions tf, zpk, ss, and frd create transfer function models, zero-pole-gain models, state-space models, and frequency response data models, respectively. These functions take the model data as input and produce TF, ZPK, SS, or FRD objects that store this data in a single MATLAB variable. This section shows how to create continuous or discrete, SISO or MIMO LTI models with tf, zpk, ss, and frd.

This section contains the following topics:

• Transfer Function Models
• Zero-Pole-Gain Models
• State-Space Models
• Descriptor State-Space Models
• Frequency Response Data (FRD) Models
• Discrete-Time Models
• Data Retrieval
