Automatic flatness control strategy with a Smith predictor for steel strip rolling

摘要：

The simplified transfer function diagram block for a automatic flatness control (AFC) system of strip steel rolling process was investigated. For the problem of automatic flatness control (AFC) in cold tandem mills this paper proposes control techniques based on Smith predictor to compensate for the numerous delays present in the mill. After a Smith predictor was used to the AFC system, the control laws were deduced for both proportional and integral regulators. Control algorithms are tested in simulation considering a tandem mill with four stands as a benchmark, and results are shown to demonstrate the performance of the proposed schemes.
