Module 4. MATLAB LTI Models

The MATLAB Control Toolbox stores linear time invariant (LTI) models as objects. These objects can be manipulated (added, multiplied) to form more complex objects. Models can easily be transformed from one form to another (state space to transfer function, for example). Continuous models can also be transformed to discrete (and vice versa).

The sections of this module are as follows:

M4.1 Forming Continuous-Time Models

M4.2 Forming Discrete-Time Models

M4.3 Converting Continuous Models to Discrete

M4.4 Converting Discrete Models to Continuous

M4.5 Step and Impulse Responses

M4.6 Summary

The majority of the functions that are used in this textbook are in Section M4.1.
