摘要
针对工业数控技术对高精度实时多轴伺服运动控制系统的发展要求,提出了一种基于ARM的嵌入式多轴伺服运动控制器的设计方案。该方案采用ARM+多单片机组合的体系结构,运用集中控制及分层处理的结构思想,实现多轴伺服电机高精度、高实时控制。运动控制器中主从系统利用USB2.0总线及CAN总线实现网络通信,能够更好地满足数控系统实时性的要求。介绍了嵌入式多轴伺服运动控制器的硬件结构,并给出了系统软件实现的程序结构框架。试验结果表明,该系统具有成本低、集成度高、精度高、扩展性强、实时性强等优点。
Aiming at the problems that the performance of multi-axis motion control system such as openness, real-time, machining accuracy is more and more important with the development of NC technology, a high-speed and high-precision multi-axis motion controller design was presented. The system uses ARM + architecture-specific integrated chip to realize the control of multi-axis servo motor, and makes use of the sttucture thought of centralized control and hierarchical processing. The master-slave control system uses USB2.0 bus and CAN bus to realize network communication, to better meet the real-time requirements of the CNC system. This article described the design of the overall motion controller hardware structure and main modules, and presented the structure of the system software framework program implementation. The experimental results show that the system has advantages of high integration, high precision, real-time and high reliability.
