Generate a timer from 0 to the required period and when it reaches the period the timer must reset and start again

I want to generate a timer which runs from 0 to the required time given and when the time is reached, the timer must reset and must start again from 0 to the time period this must happen until the stop time of the simulink is reached.

I tried with resettable system, mod and ramp block but nothing gives the required output

Hi,

I understand that you're trying to implement a periodic timer in Simulink, which resets after reaching a specified time and starts over until the simulation stop time is reached.

A combination of the following Simulink blocks can be used to achieve this:

• "Clock" block to monitor the current simulation time,
• "Constant" block to set the desired timer duration, and
• "Mod" block to implement the periodic reset.

Here is an example:

The output from the "Mod" block yields the current simulation time modulo the specified timer duration, which is essentially performing the reset operation.

Here’s the output of the “Scope” block:

The model has been attached for reference. Hope this helps.

Best,
