“…At the same time, there are increasing demands for synchronization performance of distributed motion control system (Sauter, 2007;Proenza and Vitturi, 2010). Many systems could control peripherals with synchronization accuracy in microseconds or sub-microseconds level (Cavalaglio Camargo Molano and Rubini, 2018;Chen et al, 2006). Its synchronization performance can be further improved.…”

Purpose This paper aims to analyze the key factors influencing the synchronization performance of distributed motion control system and to improve the synchronization performance for peripherals control of this system. Design/methodology/approach This paper deals with the software synchronization problems of distributed motion control system based on real-time Ethernet. First, combined with communication and control tasks, the key factors affecting synchronization performance of system are analyzed. Then, aiming at key factors and considering the synchronization of system bus, protocol conversion and task scheduling, a software synchronization method based on CANopen protocol and real-time Ethernet is proposed. Finally, the feasibility of this method is verified by establishing distributed motion control system and testing the synchronization performance of terminal control signals of slaves. Findings Based on this method, the results show that the synchronization accuracy for peripherals control of all slaves could be about 100 ns. Practical implications This research provides high-precision synchronization method, which could lay a foundation for the application of distributed motion control system in the field of assembly automation, such as multi-axis assembly robots control. Originality/value In distributed motion control system, many factors affect the synchronization performance. At present, there is no synchronization method that could comprehensively consider these factors. This paper not only analyzes the key factors influencing the synchronization performance of system but also proposes a synchronization method. Therefore, the method proposed in this paper has certain theoretical value and engineering significance.

“…The development of synchronization approaches for industrial control systems has been under extensive development recently [12] and the motion control software of modern programmable logic controllers (PLCs) has been under continuous development. The objective of this paper is to analyze the performance limitations related to the standard synchronization approaches when a biaxial (x1, x2) tooth belt drive system is controlled with a cascaded PID-based control law.…”
