Abstract
PURPOSE: To practice a thickness control while holding the time lag of a screw position controlling system constant and compensating the phase delay, by giving a phase compensation reference signal to a screw position controller of the second stand, correspondingly to a thickness variation on the run-out side of the first stand, that is a thickness variation uncontrollable by a screw position controller of the first stand.
CONSTITUTION: A screw position controller of the first stand operates the thickness of a rolled material and drives a rolling roll so as to equalize this operated thickness signal with a reference value; between this screw position controller of the first stand and a screw position controller of the second stand, a phase delay compensator, having a phase characteristic for compensating a phase delay of a screw position controller, is installed. Hereupon, a thickness deviation signal, uncontrollable by the screw position controller of the first stand, is sent to an adder through the phase delay compensator; the adder then computes a reference correction value and sends it to the screw position controller of the second stand.
