Abstract

The invention discloses a servo driving method on the basis of an electric cylinder. The servo driving method comprises the following steps that: an electric cylinder servo driving system is set up; a CPU (Central Processing Unit) board (6) acquires data of an encoder (8) and sends the data to an upper computer (5); an analog-to-digital conversion circuit (7) outputs a control signal of an electric cylinder (1) to a servo driver (2); the servo driver (2) drives an electric motor (3) to rotate; the electric motor (3) drives a speed reducer to rotate so as to ensure the electric cylinder to generate the linear motion; and the upper computer (5) detects the signal of the encoder (8) on the electric cylinder in real time so as to accurately control the protruding length of the electric cylinder. The method solves the problems of low accuracy and long leveling time which are caused by the case that a launching vehicle leveling system is driven by an electro-hydraulic servo.

Description

technical field [0001] The invention relates to a servo driving method, in particular to a servo driving method based on an electric cylinder. Background technique [0002] At present, the generalized electric cylinder servo drive method is widely used. Usually, the host computer calculates the control data in real time through the CPU board, and the control data is output to the servo driver through the analog-to-digital conversion circuit. The servo driver outputs the amplitude of the voltage according to the analog-to-digital conversion circuit. To control the operation of the motor, so that the electric cylinder produces linear motion. Since the system is an open-loop servo control system, there is no sensor to detect the length of the electric cylinder, so the control accuracy is low. Contents of the invention [0003] The purpose of the present invention is to provide a servo drive method based on an electric cylinder to solve the problem of low control precision in ...
