Abstract

The invention discloses a double-electric-cylinder synchronous control method based on multi-ring absolute encoders, which is realized through a double-electric-cylinder control system based on the multi-ring absolute encoders. A power supply (8) supplies power for electric equipment; a multi-ring absolute encoder A (6) and a multi-ring absolute encoder B (7) respectively detect rotation angles for lead screws of an electric cylinder A (4) and an electric cylinder B (5); a computing module (11) arranged in a computer (1) computes strokes of the electric cylinder A (4) and the electric cylinder B (5) through an SSI (server side include) interface board (10); a control module (12) arranged in the computer (1) outputs control signals through a motion control board (9); and a motor driver A (2) and a motor driver B (3) respectively control the operation of the electric cylinder A (4) and the electric cylinder B (5). The method provided by the invention has the advantages of high synchronous precision and high reliability.

Description

technical field [0001] The invention relates to a method for synchronous control of double electric cylinders, in particular to a method for synchronous control of double electric cylinders based on a multi-turn absolute value encoder. Background technique [0002] The electric cylinder is an actuator that converts the rotational motion of the motor into linear motion through mechanical components such as ball screws. In the occasion where double electric cylinders are required, the operation of double electric cylinders is often required to have a certain degree of synchronization. There are generally two methods for synchronous control of double electric cylinders: [0003] The first method is to install a mechanical connecting rod between the two electric cylinders, and the connecting rod ensures the synchronization of the double electric cylinders. The mechanical synchronization method using the connecting rod has certain limitations: first, it is inconvenient to insta...
