摘要
本文提出了用软件实现过程计算机控制系统中抗干扰问题的方法 ,并介绍了各种数字滤波的算法思想 .考虑到采样周期对滤波算法的影响 ,本文又对系统信号输入过程中的采样问题进行了简要探讨 .
This article presents the methods of solving the interference problems in the process computer control system by software algorithms .We produced all kinds of algorithm ideas of digital filter. Considering the influence of sampling period to the digital filter, we also simply introduced the sampling problem in the input process of the system signals.
