Today, we are going to discuss External Mode Execution in Simulink. Can anyone share what they think External Mode might do?
I think it has something to do with running simulations while observing their data.
That's right, Student_1! External Mode Execution allows us to execute models on host or target systems while monitoring critical data. This is particularly useful in real-time applications.
So, is it possible to adjust parameters while the model is running?
Exactly! This feature helps us modify parameters in real-time without stopping the simulation. Remember, we can observe data in real-time, making our simulations more interactive.
Can you give an example of where this might be applied?
Sure! It's often used in control systems where immediate feedback is necessary to adjust the system's performance. Think of aircraft control systems that require real-time adjustments.
In summary, External Mode Execution enhances our ability to develop and validate real-time systems efficiently.
