Stateflow User's Guide

Opening the Diagram for a Stateflow Block

You use Stateflow blocks to program the control of an object in the physical plant that you model in Simulink. For example, you might want the Stateflow block to decide if plant pressure or temperature is too high and make a decision to turn on a motor-driven device to reduce plant temperature or pressure. You program this control in a Stateflow diagram for a Stateflow block in Simulink.

Open the Stateflow diagram for the Controller block as follows:

1. In the Simulink window, double-click the Controller block.

1. An empty Stateflow diagram editor window appears, as shown.

   

   In the empty window you just opened, notice the following:

   • The name of the Stateflow block for the diagram you are editing (Controller) appears in the title bar of the window preceded by its owning Simulink model (SFcontrol1).
   • The toolbar on the left is for drawing the different graphical objects that compose a Stateflow diagram. Take note of the drawing tools that you use in drawing a Stateflow diagram for the Controller block in this section: the State tool and the Default Transition tool.
