MPC tunning

[Vicky Vicky]

Hi Barp, Andy C, Odessy27, Angela and all the NI engineers!!!!

I have implemented an MPC controller for

a 4 tank process that is controlled by 2 controller

values. I am having issues with the tunning for more

than one week now, I posted messages for help and suggestions

but haven't got any replies since. Please, I beg you all to have a

look at my VI and help me with this issue. I am afraid of meeting

my deadline....somebody help me!!!

Hello Vicky Vicky,

Could you explain a bit more on the issues that you are having? Also, could you include a subVI that you have Discretization VI?

for help in the MPC tunning. Please help help help

I am at a fixed for deadline!!!!

I have tried the tunning for more than 1 week now, 

but the output is not able to track the set point as 

expected. And the simulation speed seems a bit slow,

even the fact that I have a very good new PC.

Please help with this tunning and other advices for

handling MPC issues.

Hi Andy Chang, Barp, and all the engineers...

Please you guys should help with my implemented

MPC controller. The tunning has been been hard for

me for almost 2 weeks now. The output is not tracking

the set point correctly and I don't know the reason.

I have attached the main VI and dependent VIs earlier,

someone should help me please please please!!!!!

warm regards to all!!!

Hi

Can you describe you problem in more detail? It not possible to find the problem just looking at the code.

To get good answers on the forum you need to describe the problem better.

Hi EspenR,

My problem is that I have tried tunning the

MPC implemented. After tunning, if I give any set point change,

the output is not able to track the set point as expected.

It will just remain there for the whole length of time. I need

help with that please!!!!

and have tried making all the adjustments on the

weighting matrices...what else do I need to do ???

am just tired of this VI.!!!!!
