Abstract :
In-process adjustment of the blank holder force can lead to higher formability and accuracy, and better part consistency. There are many studies on the application of process control to sheet metal forming. However, process controller design has not been thoroughly addressed, and is studied in this paper. A constant gain proportional plus integral (PI) controller with approximate inverse dynamics is presented to achieve small tracking error regardless of model uncertainty and disturbances
