Title:
DIGITAL SERVO SYSTEM
Document Type and Number:
WIPO Patent Application WO/1988/003677
Kind Code:
A1
Abstract:
A digital servo system capable of quickly bringing an object having a small frictional resistance into halt at a position where it is to be stopped without generating vibration. A velocity command generation means (3) calculates a velocity command value (Vcmd) from a deviation between a position feedback and a position command value detected by the position deviation detection means (2). A velocity deviation detection means (5) calculates a deviation (E) between the velocity command value (Vcmd) and a velocity feedback. A torque command generation means (6) calculates a torque command value (Tcmd) obtained by delaying the deviation (E), and sends it to a motor drive means (7).
