摘要
针对多变量大纯滞后强耦合控制系统的设计研究,采用了多变量系统信号解耦方法和大纯滞后系统的内模控制方法。通过对大滞后系统的信号解耦方法研究,提出了大滞后耦合系统信号解耦的"耦合特征矩阵"的构造方法,给出了大滞后系统的"能解耦准则"和"系统完全动态解耦准则",以及信号解耦系统设计的"分离原理"和信号解耦系统的"稳定性判据"。实例表明信号解耦方法对大纯滞后耦合控制系统的设计非常简洁方便。
Considering the design of multivariable and strong coupling control system with big time lag,the signal-decoupling method for multivariable system and the internal model control method for the system with big time lag were employed,and then,a construction method of coupling characteristic matrix for the signal-decoupling of coupling system with big time lag was put forward,including decoupable criterion,dynamic decoupling criterion,separation principle and signal decoupler stability criterion.Examples prove conciseness and convenience of this signal-decoupling method for the coupling system with big time lag.
