SUMMARY

The discussion focuses on the application of Model Predictive Control (MPC) to the ASTROM & BELL BOILER model, specifically addressing challenges in managing constant disturbances that lead to steady-state errors in drum level regulation. The user, Syed, has attempted to implement Integral control alongside MPC and also explored feedforward strategies, yet has not achieved the desired output stability. A key insight from the discussion emphasizes the necessity of incorporating integral feedback to eliminate steady-state errors effectively.

PREREQUISITES
  • Understanding of Model Predictive Control (MPC)
  • Familiarity with the ASTROM & BELL BOILER model
  • Knowledge of integral control techniques
  • Experience with feedforward control strategies
NEXT STEPS
  • Research the implementation of integral feedback in MPC systems
  • Explore advanced techniques for disturbance rejection in control systems
  • Study relevant academic papers on feedforward control in boiler systems
  • Investigate simulation tools for modeling the ASTROM & BELL BOILER with MPC
USEFUL FOR

Control engineers, process automation specialists, and researchers focused on optimizing boiler control systems using Model Predictive Control and integral feedback techniques.

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.
