摘　　要：为了得到解耦系统设计的新方法,经过对多变量耦合系统的输出信号分析,发现在开环系统上叠加一个与耦合作用相反的解耦信号可以实现系统解耦。通过信号解耦问题的深入研究,提出了"耦合特征矩阵"的构造方法,给出了系统的"能解耦准则"和系统"完全动态解耦准则",通过对系统稳定性分析,得到了信号解耦统设计的"分离定理"以及信号解耦器的"稳定判据"。单元机组解耦控制系统仿真表明信号解耦设计方法简便有效。In order to obtain simple design method of decoupling system, based on analysis of multivariable coupled system, it is found that the signal decoupling can be realized by superposing signal with opposite sign in the open loop system. Through the research, we put forward the ＇ coupling characteristic matrix＇ of the construction method, ＇ decoupable criteria＇ and ＇ full dynamic decoupling criteria＇. Moreover stability analysis of the system introduces the ＇ separation theorem＇ of system design and ＇ stability criterion＇ of the signal decoupling controller. As to support the conclusion, the decoupling system simulation of the unit generator shows that the signal decoupling design method is both simple and effective.
