| 摘 要： | 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。

| Abstract: | 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. |
