舞台控制中的噪声分析及滤波器设计

Noise Analyzing and Design of Filter for Stage Equipment Control

１引言舞台机械过程控制中存在大量的噪声，其直接影响了舞台的控制效果。我们通过比较模拟滤波器与数字滤波器的优缺点，重点分析了数字滤波器的设计原理方法，设计了一种滤波器，应用在舞台机械主从分布群控系统中，取得了较好的控制效果。２噪声分析在舞台机械控制过程...

In this paper we discussed the source and effect of noise in stage equipment control. Comparing advantage and shortcoming of Analogic Filter with Digital Filter,we primly analyzed the principles and methods of Digital Filter designation. Applied to the distribute control system of stage equipment,this method had merits of higher control precision and calculating speed.
