在微机工业控制系统中,由于控制对象的环境比较恶劣,干扰较多,为了提高系统的性能,在进行数据处理和PID调节控制之前,一般先对采样值进行数字滤波.所谓数字滤波,是通过程序对信号进行平滑加工,提高其有用信号,消除或减少各种干扰和噪音,以保证计算机系统的可靠性.目前,数字滤波的方法有多种,我们可以根据不同的测量参数进行选择.下面介绍几种常用的数字滤波方法.
In the microcomputer industrial control system, because the control object environment is worse, the interference is more, in order to improve the system performance, before carries on the data processing and the PID adjustment control, generally first on the sampling value carries on the digital filtering.The so-called digital filter, Program to smooth the signal processing to improve its useful signal to eliminate or reduce a variety of interference and noise in order to ensure the reliability of the computer system.Nowadays, there are a variety of digital filtering methods, we can choose according to different measurement parameters. Introduce several commonly used digital filtering methods.
