Particle Swarm Optimization using parallel computing

This submission illustrates how to use a parallel computing loop to perform an optimization of the process that has been represented in Simulink.
The aim of this submission is to provide You a tool that you can adjust and apply it for your own study. Therefore the presented process is simple. The optimization problem presented in this submission concerns the selection of gains for a PI controller.
Base on this submission you might create your own code/model to solve optimization problems.
You can find examples of the use of the PSO (run in parallel computing mode) in:
