Engineering evaluation demonstrates hierarchical self-tuning temperature control in continuous annealing furnaces, highlighting robust tracking during operational setup changes.

Key Points

To develop and apply a hierarchical model-based self-tuning control system for strip temperature regulation in continuous annealing heating furnaces.
Derived a simplified mathematical furnace model from first principles.
Estimated parameters dynamically using recursive parameter estimation with a vector-type variable forgetting factor (REVVF).
Structured a hierarchical architecture combining upper-level optimal preview control for setup changes with lower-level pole-placement and generalized predictive self-tuning tracking control.
Optimal preview control successfully coordinated line speed and preset temperature trajectories during variations in strip dimensions and reference temperatures.
Generalized predictive and pole-placement self-tuning controllers maintained accurate trajectory tracking in operational industrial plant deployments.
