How Can Integral Feedback Improve Model Predictive Control in Boiler Systems?

[syed334]

Hi All,

I am applying model predictive control to the ASTROM & BELL BOILER model, I am facing difficulty in handling constant disturbance, I am unbale to reject constant input disturbance, due to which my output drum level is having steady state error, I have applied INtegral + MPC to over come STEADY STATE ERROR, but still DRUM LEVEL is not regulating back to zero
( reference value) , then I have applied feedforward + Mpc, still iam not able to track my output, can anyone help me in solving this problem, by FEEDFORWARD+MPC coding or any other way.
U can suggest any paper referring this as well.

Thanking You,
Syed

Where is the feedback part of the control? If you want zero stead state error, then there must be some integral feedback component.
