Advanced Control for Hot Rolling Mills

  • M. J. Grimble
  • G. Hearns

Summary

Hot strip rolling mills are characterised by a process which has many interactions, is distributed with dominant transport delays and has a lack of measurements due to the severe environment. There is ever increasing market demand for better product quality of the steel strip hence the requirement for higher performance controllers. The performance and robustness benefits using H-infinity controllers with a decentralised structure are examined using an advanced simulation of a hot mill.
