Title:
MOTION CONTROL METHOD
Document Type and Number:
Japanese Patent JPS63143611
Kind Code:
A
Abstract:
PURPOSE:To control rapid or highly oscillated motion by applying force or the moment of force in the reverse direction against speed when displacement is applied in the same direction as that of the speed. CONSTITUTION:When displacement (x) is applied in the same direction as the speed (v), a prescribed pulse voltage V for allowing current to flow so that force is applied in the reverse direction against that of the speed (v) is impressed to an electromagnet 22a. When a body 10 to be controlled is moved upward on the upper part of a reference position, a pulse voltage is impressed to the electromagnet 22a by a control circuit 18, current i1 is allowed to flow and an iron core 20 is sucked to the electromagnet 22a to apply down force P1 to the body 10 to be controlled. When the body 10 is moved downward on the lower part of the reference position, a pulse voltage is impressed from the control circuit 18 to the electromagnet 22b, current i2 is allowed to flow and the iron core 20 is sucked to the electromagnet 22a to apply upward force P2 to the body 10. Current is allowed to flow into horizontal electromagnets 22c, 22d similarly.
