ABSTRACT:
A position control system uses a speed command supplied to a driving source. The speed command has a change pattern which has an acceleration section (1) for eliminating a dead zone of a power transmission mechanism, a constant-speed section (or an acceleration section with a slower acceleration than in the section (1)), an acceleration section (3) up to the maximum speed, a constant-speed section (4), a deceleration section (5), a constant-speed section (6) for eliminating the dead zone (or a deceleration section with a slower deceleration than in the section (5)), and a deceleration (7) for stopping at a target section. Even when a driven member has large inertia, the position thereof is accurately controlled to the target position in a semi-closed position control system.
