Abstract

The invention discloses a synchronous control system and method based on repetitive motion multi-axis control. The synchronous control system and method have the characteristics of good synchronization performance, high reliability, good universality and the like. According to the invention, time scale is issued through an internal bus, and a driving device adopts the self time scale in a time scale interval, so that the time scale unification of the driving device is ensured, and the synchronism is ensured; phase deviation is calculated at a fixed moment, so that the calculated amount is reduced; the phase difference of final operation of the driving device is improved by adjusting the phase difference of the issued instruction, so that the synchronism of the control device is improved; the internal bus is connected with the driving device, and the number of the driving devices which can be synchronized is determined by the communication speed and number of the internal bus, so that aplurality of driving devices can be hung; and the system is easy to implement, data of the driving modules are uploaded to the bus, and the synchronous control device stores and records the data through the bus and transmits the data out through an external interface in the later period.

Description

Technical field

[0001] The present invention relates to a synchronous control system and method based on repetitive motion multi-axis control, with a good synchronous performance, high reliability, good versatility. Background technique

[0002] In a series of water bionic projects, repetition is the driving force for ensuring the operation of the diving, and the phase angle between the motors is to ensure the stability of the diving, and the multiple motors need to be synchronously controlled in the past. , Usually by the upper machine directly, each motor is swinging according to the instruction, since the motor control always lags the angular adjustment, so that the current change rate is large, it is difficult to ensure smooth operation of the drive unit, and cannot guarantee the phase angle Constant deviation; there is currently controlled and drive integrated design considerations, and generates instructions, such a benefit is strong in synchronous performance, and the runn...
