To design a stable and fully-controllable process for conveying steel plate with less noise, feasibility of incorporating the structure that can provide appropriate extra electromagnetic attraction forces has been extensively investigated. By implementing appropriate fixed electromagnetic poles on top of the rollers at the run-out-table of a steel mill, controllable lift and propulsive forces can thus be provided to drive the movable steel plate to the desired two-dimensional directions. Based on the stringent operational environment at a steel mill, an on-line recursive gap detection scheme combined with a real-time fuzzy-based controller has been developed. Realization results showed that the system, being implemented with the proposed fine-tuned processing/control scheme, can supply rapid and accurate online 2-D controls onto the steel plates and thus fulfill the design and operational objectives.
