| 摘 要： | 本文首先提出一种适用于任意反馈结构的固定模的新判据,借助于此判据不仅可以确定固定模。而且能确定固定模的重数。在新判据的基础上,作者给出一种计算固定多项式的算法,求解该固定多项式,即可得到系统的全部固定模。最后作者定义了可变模和可变多项式的概念,并对可变多项式和固定多项式分别进行了逐阶分解和逐阶扩充,阐述了分散控制系统固定模生成的机理。

| Abstract: | In this paper,a new criterion for fixed modes is presented,which may be used to determine the fixed modes as well as their multiplicities under arbitrary feedback structures.On this basis,a new algorithm for evaluating fixde polynomial is given.By solving this fixed polynomial,the fixed modes may easily be obtained.Finally,new concepts of variable modes and variable polynomial are introduced and the occurrence of fixed modes in decentralized control systems is explained through successive decomposition of the variable polynomial and expansion of the fixed polynomial. |
