Abstract:

Towards the requirements of ultra-precise synchronous motion control in stage application, a design for parallel computing architecture for multi-axis synchronous motion was proposed. This paper introduced hierarchical structure of the motion control system, and defined an internal bus protocol to implement high performance data transmission network among multiple motion controllers, in which stable bandwidth and precise transmission latency were achieved. According to the characteristics of synchronous motion of the stages,strict parallel cycle plan and synchronization mechanism were designed to implement synchronization of distributed algorithms for multi-axis motion control. Experimental results show the validity of parallel computing architecture.

Key words: parallel computing architecture, precision, motion control, synchronization
