摘要
针对运动控制系统对高速度与高精度的要求,基于二次插补原理及最小偏差插补法,提出一种以PC机为主控制器、FPGA为从控制器的主从式运动控制系统的设计。主控制器的功能是对系统运行过程进行控制规划和粗插补;从控制器的功能是对加工进行精插补和执行速度控制。该系统在Matlab环境下进行了插补仿真,并在两轴数控雕刻床上进行了加工测试,验证了系统的可靠性与高精度。加工精度可达0.01 mm,为高精度、高速插补数控系统提供了有效的解决方案。
In allusion to the demand for high precision and high speed from the motion control system, based on the twice interpolating algorithm and the least deviation interpolation, a design for master-slave motion control system based on PC as the master controller and FPGA as the slave controller is presented. The function of the master controller is control programme and first interpolation, and the function of the slave controller is second interpolation and velocity compensation. This system has been simulated in Matlab, and tested on the two-axes carving machine. The result shows the system is high reliable and high precise, the machining accuracy is 0.01 mm, and present a perfect solution for high-precision and high-velocity interpolating CNC system.
