SERVO CONTROL SYSTEM WITH POSITION COMPENSATION FUNCTION FOR DRIVEN MEMBER
First Claim
1. A servo control system comprising:
- a servo motor;
a driven member driven by the servo motor;
a coupling mechanism coupled with the servo motor and the driven member, the coupling mechanism using the servo motor as a power source to generate a drive force acting on the driven member at a coupling part of the driven member and the coupling mechanism; and
a motor control part controlling the servo motor, whereinthe motor control part comprisesa position command generating part generating a position command value of the driven member,a force estimating part estimating the drive force acting on the driven member at the coupling part,a compensating part compensating the position command value generated by the position command generating part based on the drive force estimated by the force estimating part, anda control signal output part outputting a control signal to the servo motor based on a position command value compensated by the compensating part.

Abstract
A servo control system including a servo motor, a driven member driven, a coupling mechanism coupled with the servo motor and the driven member, and a motor control part controlling the servo motor. The motor control part includes a position command generating part generating a position command value of the driven member, a force estimating part estimating the drive force acting on the driven member, a compensating part compensating the position command value based on the drive force estimated by the force estimating part, and a control signal output part outputting a control signal to the servo motor based on a position command value compensated by the compensating part.
