实时跟踪控制系统中的数字滤波技术

Digital Filtering Technique in Real Time Tracking and Control System

在高精度的实时跟踪控制系统中，由探测器等其他一些因素给系统带来的噪声将不容忽视，数字滤波将是滤除噪声的有效手段，由于系统实时性和采样频率的要求，并非所有的数字滤波器均能在实时系统中应用，本文介绍几种实时跟踪系统中常用的数字滤波方法，并对它们在实时跟踪系统中的作用进行了分析和比较。

The noise in the high precision real time tracking and control system introduced by detectors and some other factors cannot be ignored ,The digital filtering technique is an effective approach for eliminating noise.Not all the digital filters can be applied to the real time system because of the requirements of the system real time character and sampling frequency.The several digital filtering methods often used in the real time tracking system are introduced in the paper,Their functions in the real time tracking systems are analyzed and compared.
