ABSTRACT:
Driving a dividing shear to a home position after cutting a workpiece is done without oscillations at the home position. Control uses shear position feedback signal to shape nonlinearly a variable shear velocity reference signal such that no overshoot occurs. Adaptive control procedure automatically adjusts variable shear velocity reference signal to compensate for dynamic changes in cutting operation.
