AI Technical Summary

Problems solved by technology

This requires multiple motion controllers to coordinate the control of these servo motor shafts, so there is a problem of synchronous control of the multi-motion controllers. If the synchronization problem is not solved properly, the wave-making accuracy will deteriorate and the wave-making quality will be seriously affected.

Abstract

The invention discloses a wave machine control system based on multi-controller synchronous control. The wave machine control system comprises a host computer, a main controller, slave controllers, anEtherCAT bridge and a wave making unit. The host computer transmits control instruction information for the wave machine to the main controller in real time, the main controller transmits the controlinstruction to the plurality of slave controllers in real time, the slave controllers transmit the control instruction information of the wave machine to the wave making unit in real time, the wave making unit makes waves according to the control instruction information; wherein the master controller and the slave controllers are all PC-based soft PLCs. The system achieves the effect of multi-controller synchronous control through the EtherCAT bridge, so that a large wave-making system having hundreds of servo axes can also be synchronously controlled, and the synchronous control has high precision and good real-time performance.

Description

technical field [0001] The invention relates to the field of ocean wave simulation, in particular to a wave generator control system based on multi-controller synchronous control. Background technique [0002] At present, in the engineering fields such as marine and shipbuilding, wave generators are often used in the laboratory to simulate sea waves, act on the model, and verify various indicators of engineering design. With the development of technology, the contemporary wave generator system usually uses a synchronous servo motor to drive the wave generator to achieve high real-time performance with high control precision and fast response. This wave-making system usually consists of a host computer, a motion controller, a servo driver, a synchronous servo motor and a wave-making unit. Due to the limited computing performance of a single motion controller, it can only control dozens of servo motor shafts, while large-scale wave-making systems usually require hundreds of s...
