用前馈补偿法对双输入双输出系统（TITO）时滞系统进行解耦,有些系统的补偿器往往会含有超前环节,无法用器件实现。针对这一问题,该文提出了一种近似方法：把超前环节展开成泰勒级数,根据精度要求取前几项。该文通过Simulink软件对实例进行了仿真分析,证实了用这种方法设计的补偿器非常简单,能很好地实现解耦。这种近似的补偿器也可以用硬件和软件实现,所以这种方法是有实用价值的解耦法。
用前饋補償法對雙輸入雙輸齣繫統（TITO）時滯繫統進行解耦,有些繫統的補償器往往會含有超前環節,無法用器件實現。針對這一問題,該文提齣瞭一種近似方法：把超前環節展開成泰勒級數,根據精度要求取前幾項。該文通過Simulink軟件對實例進行瞭倣真分析,證實瞭用這種方法設計的補償器非常簡單,能很好地實現解耦。這種近似的補償器也可以用硬件和軟件實現,所以這種方法是有實用價值的解耦法。

If the time-delay TITO （Two inputs and Two outputs） systems are decoupled by feedforward decoupling methods,some of the systems are often given the compensators with lead elements which can not be implemented by using components.To solve this problem,this paper presents a method of Taylor expansion of lead elements which seek several items according to the precision.The simulation and the analysis to the examples is done by Simulink software,which confirmed that the design of compensation method is very simple and can realize the decoupling well.This kind of approximate compensator also may be realized by the hardware and the software.Therefore,this method has the practical value.
