MIMO系统的分散控制研究

Decentralized Control of Multiple Input Multiple Output System

ＤＣＳ已广泛应用于工业生产过程，但其许多功能还没有充分发挥．分散控制的基础是解耦，根据耦合度的概念，提出分离最大耦合度的配对控制支路，使ＭＩＭＯ系统的整体耦合度弱化．采用这种方法，可以方便地将一个ｎ×ｎ的ＭＩＭＯ系统分散成ｎ个ＳＩＳＯ系统．仿真试验证实本方法有良好的效果，这种分散ＭＩＭＯ成为ＳＩＳＯ系统的方法在集散系统中有广泛应用．

Basing on the degree of coupling as a new concept,the authors advance the pairing control shunt to separate maximal degree of coupling.This will weaken the degree of the global coupling of multiple input multiple output(MIMO)system.By adopting this method,a n×n MIMO system can easily be decentralized into n single input single output (SISO) systems.As a method confirmed by simulation experiment to have good effect,this method has been widely applied to centralized and decentralized systems.
