6/401425

Inventors:

Bhupendra S. Surana - East Amherst NY
William H. Snedden - Newstead NY

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

G06G 726

US Classification:

364469

Abstract:

A programmable controller including coil diameter calculator and strip speed derivation and inertia compensation is associated with a reel system for the generation in normalized digital form of the coil diameter of the reel instantaneously to allow initial calibration between successive coil winding and unwinding operations and automatic generation of a current reference for reel motor drive control.
