Abstract: Mill control system and method for metal strip rolling controlled in response to a sequence of controller scans are provided. A sensor suite is coupled to sense a plurality of parameters regarding the strip rolling. A model responsive to the sensed parameters is configured to estimate per scan at least one matrix based on the sensed parameters and indicative of state conditions of the strip rolling. A controller includes an inner control loop configured to effect a control law to generate a control vector per scan. The inner control loop may be configured to have dynamic characteristics, which remain substantially the same for each scan of the controller. The dynamic characteristics of the inner control loop are effective to determine a pointwise online control solution based on the matrix indicative of the state conditions of the strip rolling, without having to compute a Riccati control solution per scan.

Abstract: The invention generally relates to a method of controlled rolling of a metal strip moving through a rolling mill. The method comprises: monitoring a plurality of input control parameters; and generating a plurality of responsive operational control parameters in the rolling mill to selectively control the rolling mill and selectively control a plurality of output parameters of the rolling mill. A control system for controlled rolling of a metal strip moving through a rolling mill is also provided.
