非对消解耦设计中对绝对不稳定的一个判据

本文讨论了应用非对消法对非最小相位对象进行解耦设计的问题，指出应用中存在着一类非最小相位对象，其输出响应对操作变量干扰存在着闭环绝对不稳定，文中给出了一种实用判据。

The Criterion of Absolute Unstability in Non cancellation Decoupling Design

The paper discusses the problem of decoupling design of non minimum phase shift objects using non cancellation method and has discovered that one kind of the object should be excluded, because output response will lead to closed loop absolute unstability to operating variable disturbance. A practical criterion has been given in this paper.
