摘要
针对光信号转换成电信号后仍然存在不利频率成分的问题,对π型滤波电路在伺服系统中的具体应用进行研究。从滤波器的各种分类出发,介绍π型滤波电路的基本原理,并结合工程项目中天线转台的抖动问题,在采样支路加入适当的电阻,形成π型滤波器,对干扰纹波起到一定的抑制作用。实际应用结果证明:角度传感器反馈的角度数据正常,天线转台能正常运转。
Aiming at the occurrence of disadvantage frequency after optical signal transforming into electric signal, research on application of n model filter circuit in servo system. Based on filter types, introduce the basic principle of n model filter circuit, combine with vibration problem of antenna turret in engineering project, add resistance in sampling branch to generate n model filter circuit. It can resist disturbance wave. The application results show that the angular sensor feedbacks normal angular data and antenna turrets run smoothly.
