摘要
本文根据相关原理提出了一种以逆重复伪随机信号为系统输入信号的相关辨识法,该法在轧机液压压下系统中的试验结果表明,它不仅能测得系统的准确动态特性,而且为大型复杂系统的在线辨识提供了一种有效手段。
This paper introduces a correlation identification method that uses negative sequence repeated pseudo-random signal as input signal of system in terms of correlation theorem. The test result in AGC system for rolling mill proves that the method is not only able to give correct dynamic characteristics of the measured system, but also provides effective means for identification on line of heavy and complex system.
