Actuator's i.e. rotation actuator, position variation suppressing method, involves computing instructions for electric current of motor drive from speed instruction and feedback values for speed

摘要

The method involves correcting position instructions and position feedback values in a feedback loop of an actuator speed control using error correction data for feedback values. Speed instruction is computed from a position deviation between the corrected values and instructions. The values are corrected from a motor position detector (6) using the error correction data, and speed feedback values are computed based on the corrected position feedback values. Instructions for electric current of a motor drive are computed from the speed instruction and feedback values for speed.
