Delaying Signal Builder Start in Simulink

Hello,

I am new to Simulink and I am seeking guidance on how to initiate the Signal Builder in Simulink only when my toggle switch is set to 1, even while the simulation is in progress. Currently, I encounter an issue where the Signal Builder starts simultaneously with the simulation. That is, I want to control when the the Signal Builder starts even while the simulation is running.

Can I please have your advice on how to achieve this?

Thank you

Try to put the Signal Builder block inside an Enabled Subsystem block.

I attempted it, but unfortunately it was unsuccessful. The Signal Builder initiates concurrently with the simulation, even inside an Enabled Subsystem block.

Do you have any additional suggestions please?

[Fangjun Jiang]

I can't think of other ways. What type and how many signals? Does it have to be Signal Builder?

[Badr]

I have only one signal that it.

[Fangjun Jiang]

This can be done through an 1-D lookup table. The trick is the input.

Use your Switch output to enable an Enabled SubSystem block. Inside, Connect Constant value 1 to an Integrator block and then to an 1-D Lookup Table block. You may neet to figure out how to reset the Integrator if you need to switch back and forth multiple times.

using an integrator block and 1-D Lookup I obtain only one value

could you please share a picture that demonstrates your explanation ?

thank you

Integration of 1 is like the clock but it will only start when the subsystem is enabled.
