Abstract

The present invention provides an offset compensation method, device, electronic equipment, and computer-readable storage medium. The method is applied to a system including a single-turn encoder and a multi-turn encoder, and includes: acquiring the current value indicated by the multi-turn encoder first position; obtain the current second position of the single-turn encoder; determine the offset angle between the first position and the second position according to the preset direction; based on the offset angle, control The multi-turn encoder moves from the first position to a target position according to the preset direction; wherein, the angle between the target position and the second position is less than or equal to a preset threshold. The embodiments of the present invention can ensure the consistency of each synchronization, and obtain stable and consistent synchronization results.

Description

technical field [0001] The present invention relates to the technical field of sensors, in particular to an offset compensation method, device, electronic equipment and computer-readable storage medium. Background technique [0002] The multi-turn encoder is a sensor that judges the rotation of the motor based on the Hall device. It can provide information on the number of rotations and the current position information provided by the Hall device. Usually, its position accuracy is low. The single-turn encoder is a sensor that can provide high-precision single-turn position information to the outside. [0003] For systems that use single-turn encoders and multi-turn encoders at the same time, due to different reasons such as equipment installation and encoder manufacturer's design, the zero position of the two rotations is not consistent. Moreover, due to the huge gap in accuracy between the two, the single-lap position information indicated by the two is not consistent, and...
