Hi Jihed ,
I understand that you are looking for a way to automatically save Simulink model at regular intervals, specifically every 5 minutes. However, Simulink currently does not have a built-in feature specifically designed for auto-saving models at regular intervals. Instead, one can achieve this functionality through MATLAB scripting and utilizing Simulink's callback functions or MATLAB timers. Here is a basic approach using MATLAB's timer functionality:
1.Create a MATLAB script for timer: This script will create a timer object that calls a function to save Simulink model at specified intervals.
function setupAutoSave(modelName, interval)
% Check if the model is open
if bdIsLoaded(modelName)
% Create a timer object
t = timer;
t.StartDelay = interval;
t.Period = interval;
t.ExecutionMode = 'fixedRate';
t.TimerFcn = @(myTimerObj, thisEvent)autoSaveModel(modelName);
start(t);
% Optional: Assign the timer to the base workspace for control
assignin('base', 'autoSaveTimer', t);
else
error('Model %s is not loaded.', modelName);
end
end
function autoSaveModel(modelName)
% Auto-save the model
fprintf('Auto-saving model: %s\n', modelName); % Optional: for verification
save_system(modelName);
end
2.Call setup function with model name and interval: Before running, ensure model is open. Replace 'yourModelName.slx' with the actual name of model, and 300 (seconds) corresponds to 5 minutes.
setupAutoSave('yourModelName.slx', 300);
This script sets up a timer that saves the specified Simulink model every 5 minutes. Adjust the interval as needed by changing the 300 to another value (in seconds).
Important points to consider:
- This method saves the model regardless of whether changes have been made since the last save. This could lead to unnecessary saves if the model is not being modified.
- Regularly saving large models may impact performance. Monitor system's performance and adjust the save interval if necessary.
- If need to stop the auto-save feature, stop, and delete the timer using the following commands in the MATLAB Command Window:
stop(autoSaveTimer);
delete(autoSaveTimer);
clear autoSaveTimer;
Make sure to assign the timer to a variable as shown in the script (autoSaveTimer in this case). This approach provides a flexible way to ensure Simulink models are regularly saved, minimizing the risk of data loss during long modelling sessions.
