  • Backlash compensation in motion control systems
    Patent number: 12013678
    Abstract: A method for backlash compensation in motion control systems includes homing a payload of a motion control system, and performing a tooth-pitch non-uniformity procedure on the motion control system to identify a non-uniformity correction. A backlash lookup table is generated for use in backlash correction during normal operation of the motion control system. The backlash lookup table is generated using a training process that includes selecting a move sequence for operating the motion control system, and executing the move sequence with the non-uniformity correction. The training process further includes computing a backlash measurement describing backlash of one or more components of the motion control system during the move sequence, and storing the backlash measurement in the backlash lookup table.
