- •
The calculation methods of encoder's errors caused by the mechanical vibrations were put forward.
- •
The influence of encoder's error caused by the mechanical vibration on the displacement fluctuation for the linear motor feed system was analyzed.
- •
The mechanism of the electromechanical coupling considering encoder's error was explored. And its effect on the motion stability of feed system was discussed.
- •
The compensation and improvement methods of the displacement fluctuation caused by encoder's errors were proposed.
