Optimizing design of control system for hot strip continuous rolling and optimum control

The optimum design schemes on tension composite optimum control system, profile and thickness coordinate optimum control and temperature control based on established velocity in hierarchical progressive intelligent control structure for hot strip continuous rolling are put forward. With rolling state equation and quadratic model object function, the closed loop optimum control on profile and thickness coordination, the best correction of roll gap in crossing process, the real time estimation of roll crown, the optimum setting of roll crown and the optimum bending force setting etc in process optimizing tactics for hot strip rolling are derived.
