Create an internal loop in Simulink simulation
11 vues (au cours des 30 derniers jours)
I am trying to create an internal loop (without using the if-loop blocks, because these seem to significantly slow down my model) to allow one part of my simulation to run for a specified number of times, and then output this so the rest of the simulation can continue. This would be the equivalent of a for loop inside a for loop, such as:
for(1:end of simulink simulation)
for(1:specified number of loops)
Run small part of simulation over and over
Run the rest of simulation
For a little context, this is for an iterative heat pump model, so that the heat pump portion can run several times to reduce error, and then the rest of the simulation can continue.
I was attempting to use a switch that is only thrown after a counter reaches a specified value, but I am unsure what to connect to the other side of the switch to prevent the rest of the simulation from continuing.

The simplest way to implement this is to use Triggered or Function-call subsystems in Simulink driven by Stateflow (for the loop logic) or Embedded MATLAB Function block (at least that's what it used to be called when I used them in R2011b). After modeling this, you can either make sure your sorted order is appropriate for this operation, or simply use Stateflow to become your task scheduler so everything runs exactly how you want it to do.
