摘要
提出一种用于非最小相位离散系统的自适应控制法，就是用最小二乘相似法得到相似逆系统。介绍如何避免非最小相位系统中不稳定极、零点相抵消的情况，以及在输出中消除干扰的问题。最后举例说明这种方法的可行性。
This paper presents a method adopting model reference adaptive control for nonminimum phase discrete time systems by using approximate inverse systems obtained from the least squares approximation.How to avoide the unstable pole zero cancellation and the interference in the plant output are introduced in this paper.Finally,the results of computer simulation are presented to illustrate the effectiveness of the proposed method.
