Simulating computation time with OpDelay

Context

I want to be able to simulate a computation charge, because I want to know the stability limit of my system. How can I do that ?

Solution

You can use the OpDelay block (RT-LAB/Monitoring Simulink library) to simulate computation time. This block will introduce a delay (this value is set in microsecond) in computation. Your stability limit is reached as soon as you get overruns ! Note that if Delay value is 0 it does not affect at all the computation time.

Please refer to attached model and attached picture.
