Position feedback
PRACTICAL WORKS
• Study of the principle of a closed feedback loop: error voltage, pre-amplification, driver stage, push-pull.
• Study of limitation of movements circuits.
• Anti-jamming system.
• Study of the feedback response to a voltage step fordifferent values of loop gain.
This model is designed for the simplified study of a closed position feedback loop. It is composed of a direct current motor, the rotation of which drives a worm-screw.
The screw cursor is integrally attached to a copying potentiometer which supplies an electrical image of its position.
The potentiometer operated manually
determines the basic position.
