Set Simulink model simulation stop time from m file
显示 更早的评论
I want to set my models simulation stop time from an m file, but I'm a little confused about how to go about it. When I'd get the data for blocks I'd use get_param, but I want to get the parameters of the model. Would I go about it the same way? Thanks.

You can set_param for the model also:
set_param('modelname', 'StopTime', '3000')

I tried this and it sets the time OK (after sim is done, I open the diagram and new value is visible), but when I run the simulation sim('test_sim') it does not take this value. Why is this happening?
Could you provide the link to documentation for StopTime?

If you are using the sim function to run your model, you can set the stop time as follows,
sim('model_name', 'StopTime', '40');

Thank you but how to set this dynamically from a parameter instead of a constant value?

You can also do it by passing it as an argument when you run the simulation from the m file:
sim_out = sim(sim_model, t_stop)

This doesn't work anymore. Has the syntax changed recently?
I get the following error:
Expected a string scalar or character vector for the parameter name.

Hmm. Not sure. Are you converting t_stop to a string? This is the exact statement I am using right now with MATLAB v2021b. Maybe you need to include the option char array like this:
sim_out = sim(sim_model, 'StartTime', '0', 'StopTime', string(t(end)));

Actually, the original code I posted above where t_stop is a number does also work in 2021b. Maybe this behaviour has been removed in recent versions. Nevertheless, maybe it's best to always include 'StopTime' and use string(t_stop).
