Stateflow User's Guide

How Stateflow Works

In Simulink, a Stateflow block uses a Stateflow diagram to represent an object with a discrete set of modes. These modes are known as states. The Stateflow finite state machine reacts to events by changing states for the controlled object. The behavior of the object depends on what state the object is in and how the object changes from one state to another.

Use the following topics to get an introductory understanding of how Stateflow works in a Simulink model:

• Stateflow Works with Simulink
• Stateflow Represents Control Modes with States
• Stateflow Changes Active States with Transitions
• Stateflow Reacts to Events
• Stateflow Chooses Destinations with Junctions
