摘要

分析了零点配置/回路传函恢复(ZP/LTR)方法稳定性

给出并证明了其稳定性条件.但该条件较为苛刻

限制了ZP/LTR方法的应用.为了对ZP/LTR方法改进

在设计过程中引入了Kal man滤波器

通过选取特殊的参数

使Kal man滤波器回路逼近并取代原目标回路

从而在保留ZP/LTR方法性能的同时

通过保证Kal man滤波器回路的稳定性保证了最后闭环系统的稳定性.给出并证明了改进后的ZP/LTR方法的稳定性条件

指出改进后的ZP/LTR方法的稳定性条件较为宽松

拓宽了原ZP/LTR方法的应用范围.

Abstract

Zero placement/loop transfer recovery(ZP/LTR) method was analyzed theoretically to find and demonstrate the conditions of stability.However

these strict conditions have placed constraint on the application of ZP/LTR method.Kalman filter was thus introduced for the purpose of improvement of ZP/LTR method.With some special parameters selected

Kalman filter loop could approximate and replace original target feedback loop(TFL).While the performance of ZP/LTR method is maintained

the stability of final closed-loop system could be guaranteed along with the stability of Kalman filter loop.The stability conditions of improved ZP/LTR method was presented and demonstrated

showing that the stability conditions of improved ZP/LTR method were less strict

thus expanding the scope of applications for original ZP/LTR method.
