中文摘要
      本文使用分散控制方法，讨论并解决了控制系统的补偿谱和闭环谱的相交性问题。文中引进了消失性的概念，得到了关于集中系统和分散系统存在使补偿器和闭环谱不相交的动态补偿器的充分必要条件。此外，该条件不成立时，给出了使用任何动态补偿器所得到的补偿谱与闭环谱的交。
英文摘要
      Using the decentralized control method, the intersection problem of compensating spectra and closed-loop spectra is considered. For centralized systems and decentralized systems respectively, we establish the necessary and sufficient conditions for a dynamic compensator to exist so that the compensating spectrum and its corresponding closed-loop spectrum do not intersect by means of the vanishing concept introduced in the present paper. In addition, the intersection of a compensating spectrum and its corresponding closed-loop spectrum is also found out when the conditions fail to hold.
