数控系统运动控制性能的测试方法研究

Research on Sampling Method of CNC Motion Control Capability

以脉冲信号为对象,研究了数字和模拟两种采集方法的测试原理和误差;设计专用算法解决了模拟采集方法存在的非实时性问题,弥补了数字采集方法测量误差大的缺点;最后给出了测试实例。

Keywords This paper, oriented towards pulse signal, researches testing theory and error range of two type sampling method between digital and simulation. Special arithmetic is developed for the problem of unreal time along with simulative signal sampling. This arithmetic remedies the limitation of digital signal sampling. At the end, an example is supplied.
