Hi Vishwajit,
To implement a sliding window mechanism in Simulink that raises a flag if three events occur within a 30-second window, you can use a combination of various Simulink blocks to manage event counting and timing. You will needd to implement the following:
- Event Detection: Use an Event Trigger block or a logical condition block to detect the occurrence of an event. This block should output a pulse or a logical 1 whenever an event occurs.
- Counter: To count the number of events. This counter should increment every time an event is detected.
- Timer: Use a Clock block to keep track of the simulation time. Use a Triggered Subsystem or a Stateflow chart to implement the timing logic. This subsystem should start timing when the first event occurs.
- Sliding Window Logic: This will be the implementation logic for Stateflow chart.
You can model the logic on the following lines:
- Start a timer when the first event occurs.
- Check if the count of events reaches three within 30 seconds.
- Reset the timer and counter if the 30-second window expires without reaching three events.
- Continue counting events and checking the 30-second condition as new events occur.
For more information you can refer to the documentation :

I hope this gives you an idea.
