A vibration table control method and system

Abstract

The present invention relates to a vibrating table control method and system. The method includes the following steps: acquiring a position time series, the position time series including a plurality of position values ​​arranged in chronological order; generating a position according to the first position value command, drive the motor to run with the position command, and control the movement of the vibrating table through the motor; when the vibrating table moves to the position corresponding to the first position value, according to the position corresponding to the first position value The next adjacent position value drives the motor to continue running; according to the remaining position values, the motor is sequentially driven to run until the vibrating table moves to a position corresponding to the last position value, and the control unit The vibrating table does reciprocating motion. The technical scheme of the invention can greatly improve the dynamic performance of the control under the condition of ensuring the positioning accuracy, and can obviously reduce the shaking when the vibrating table changes the moving direction.

Description

technical field [0001] The invention relates to the technical field of motion control, in particular to a vibration table control method and system. Background technique [0002] At present, the reciprocating motion of the vibrating table is often controlled by speed control and position control. Among them, the speed control method is fast, but the positioning accuracy is poor; the position control method has good positioning accuracy, but is driven by the acceleration and deceleration. Limitation, poor dynamic performance, easy to produce jitter during forward and reverse conversion. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a vibration table control method and system. [0004] The technical scheme that the present invention solves the problems of the technologies described above is as follows: [0005] In a first aspect, the present invention provides a vibrating table control method,...

AI Technical Summary

Problems solved by technology

[0002] At present, the reciprocating motion of the vibrating table is often controlled by two methods: speed control and position control. Among them, the speed control method is fast, but the positioning accuracy is poor; the position control method has good positioning accuracy, but is driven by acceleration and deceleration. Limitation, poor dynamic performance, easy to generate jitter during forward and reverse conversion
