[TRNSYS-users] question related to predictive control

[Georgios Kyriakarakos]

Dear Carol,

I have implemented predictive control in TRNSYS based on Grey theory. You can find the paper which describes this in the address below:
http://www.sciencedirect.com/science/article/pii/S0306261912007155
What we usually do is initially implement control algorithms in Matlab and optimize them there and when they are finalized we write the code in Fortran and add it to TRNSYS. Matlab calling is indeed very slow in comparison with a fortran added routine in TRNSYS. This time delay is increased considerably when using external optimization programs like GenOpt where a big number of simulations (~2000) have to take place.
