摘　　要：目的研究多变量耦合系统解耦设计方法,优化控制系统设计。方法采用信号解耦方法对多变量耦合系统进行解耦,通过对耦合系统传递函数阵的特点研究。结果得到了多变量信号解耦的"能解耦准则"、"完全动态解耦准则"和"解耦器稳定判据";给出了信号解耦设计的"分离原理"。结论信号解耦方法表明解耦器的存在性、可实现性和稳定性取决于耦合系统的结构及参数,重新匹配变量、部分解耦和静态解耦是其改变办法。信号解耦器设计方法简单有效,但多变量信号解耦器的连接比较复杂。Aim To research the decoupling method of the muhivariable coupling system. Methods Using the signal deeoupling method to decouple the multivariable coupling system, and research the coupling system transfer function characteristics. Results The ＂decouple-able criterion＂ , ＂dynamic decoupling criterion＂ and ＂decoupler stability criterion＂ of the muhivariable signal decoupling are obtained. The ＂separation principle＂ is got to the sig- nal decoupler design. Conclusion Signal decoupling method shows that the decoupler＇s existence, realization and stability depends on the structure and parameters of the coupling system. The variables＇re-match, part decoupling and static decoupling are the way to change it. The signal deeoupling design method is simple and effective, but the muhivariable signal decoupling connection is more complex.
