Stateflow: reset simulink-based state on entry

Question

0 个投票

I have a Stateflow chart in Simulink, and in this chart I have some Simulink-based states. Some of these states contain stateful blocks such as integrators and delays. I would like to reset some or all of the block states each time I enter the Simulink-based state. How can I achieve this?

Did you try putting a reset subsystem in the Simulink subsystem to reset the state?

Thanks.

Hi @Mark McBroom. Thanks for the reply. I tried adding a "Reinitialize Function" block to the simulink state. By itself this does nothing. I believe I need to call it's associated reinint() function, but I'm not sure how to do that on entry to the state in the stateflow chart. Could you please clarify?

I can attach the minimal test model I am working with if needed.
