Improvement of accuracy for gauge and elongation control by dynamic process control simulator

We have developed many dynamic-process-control-simulators with dynamic-properties as same as the real plant for a part of process-control-solution. And by these simulators, we have been able to diagnose the control and examine the improved control method. For example, we have made the simulators of auto-gauge-control for single cold strip mill and elongation-control for skin pass mill based on our simulator for tandem cold strip mill, and we have been able to examine the size-control for various mill types. And we have developed the automatic-identification method for parameters in the simulators instead of trial and error and then we have realized the high-accuracy and efficient creation of the simulators. Especially for continuous galvanizing line, with the control method improved by using the simulator of elongation control, we could have much improved the yield of elongation in front and behind of welding point at high speed of mill in the delivery section of furnace.
