西门子S7控制系统中数字滤波的研究与实现

Research and Implementation of Digital Filtering by Siemens S7 Control System

在计算机的自动控制系统中,经常采用数字滤波的方法来消除信号检测通道中的各种噪声及干扰。介绍了自动控制系统中常用的数字滤波方法及这些滤波算法在西门子S7系列控制器中的编程实现方法,并通过计算机仿真系统对数字滤波的效果进行了对比分析。

In the automatic control systems based on computer, the digital filter is often used to eliminate all kinds of noises and interferences in the signal detection channels. This paper introduced the methods of programming the commonly used digital filtering in automatic control system and the filtering algorithm on the SIEMENS S7 series controller. It also made a comparative analysis of the effect of computer simu-lation system on digital filtering.
