扰动补偿控制—减弱噪声对跟踪系统引起的误差

The Simulation and Influences of Noise on Control System

来自于通讯或测试系统中的噪声和外界环境干扰,对控制系统可转化为一种随机起伏的电信号,噪声对于信息的传输和处理有很大影响。对噪声的来源及如何在控制系统中消除进行了分析,并引入扰动补偿后对控制系统进行仿真,结果表明:扰动补偿控制可以减弱噪声对跟踪系统引起的误差。

Noise can be generated both by electric devices in either communication or measurement system and distrubing from environment.Such noise can turn into a kind of random and undulating electric signal in control system,noise influences on transporting and deal with of information greatly.The origins of noise are analyzed and how to eliminate noise in control system is suggested in this paper.Further more,simulation to reduced noise in control system is carried out based on compensating of disturb,results show that the error of tracking system produced by noise can be decreased though this way.
