摘要
在多参数控制系统中,控制信号由多路输入信道传输给控制单元。由于信道之间存在相互干扰,因而系统的输出受到影响。通过对输入信号的分离,去除信号之间的相互影响,恢复原始的控制信号,能够提高控制系统的性能。独立分量分析是一种盲源分离的方法,对其进行了简要介绍。用此方法对多参数控制系统输入信号进行分离,恢复出原始控制信号。通过大量的仿真试验,验证了此方法的有效性。
In multivariable control s.ystem,the multi- channels signal are transmitted to input interfaces. But there are mutual influences coming from each channel,which can make the system＇s output warped. Separating the multi- channels signal can eliminate the influence. In this paper we introduce the independence component analysis, the method in blind source separation, and use it to separate the disturbed signals, and then the original control signal could be gotten back and the performance of the system is upgraded, The simulations in this paper compared the results of original,influence and de- influence input signals. It can be proved by the simulation that the availability we used the method is perfect.
