Reference preview/look-ahead in Simulink
8 views (last 30 days)
I'm doing simulation on model predictive control (MPC) with my own designed solver (so no use of MPC toolbox) in Simulink. I'm wondering how I can implement reference preview/look-ahead in Simulink without using the MPC toolbox, like this example https://nl.mathworks.com/help/mpc/ug/improve-control-performance-with-look-ahead.html.
I'm aware that in Simulink I can use Unit-Delay and Memory to access data in the past, but I don't know how to access data in the future.
Any help is appreciated!

As I understand it, you want to use implement a look-ahead in simulink without using MPC toolbox because you have already designed your own solver.
In the example you shared as , Improving Control Performance with Look-Ahead (Previewing), there is an example of a Simulink implementation of a Future Sample Extractor with Memory blocks. That may give you some insight on how to procede.
However your best bet would be to use the MPC toolbox itself.
