MATLAB: How to visualize signals evolving time by time on a dashboard, while simulation is running

simulationsimulink

I would like to see how signals change in time, time by time and not all at once at end. I tried to understand it from the example sldemo_fuelsys (Fault-Tolerant Fuel Control System) but I could not. In few words I would like to see signals evolving on a dashboard while simulation is running.

Although you can visualize a signal using scope. But if you want to use dashboard then use Dashboard Scope in Simulink to visualize the signal. A sample file is attached.

Hi Zi,

Yes, Real-Time Windows Target is now called Simulink Desktop Real-Time. It looks like the change happed in R2015a.

MATLAB: Hide simulink editor while running a model

You can run the model without opening the model using the sim command. See doc for sim command here. You can also load the model using load_system which will load the model in memory but not open the editor. See Run Simulations Programmatically for more details.

The following will load the Modeling a Fault-Tolerant Fuel Control System example model (sldemo_fuelsys) and simulate it:

model = 'sldemo_fuelsys';
load_system(model);
set_param(model, 'SimulationCommand', 'start')

You can simulate it without opening/loading explicitly using the following:

sim('sldemo_fuelsys')
