摘　　要：本文分析了经典的频率法和改进的脉冲法进行系统识别方面的不足,讨论了相关函数法进行系统识别的原理和存在问题,最后推理得出采用弱信号提取法与相关原理结合进行系统动态在线识别的可行性,并从实用角度分析了该方法的特点和注意问题.The defects of two classical method on an linear system identification is analyzed, The principle and open questions of a correlation function analysis method on an linear system identification are discussed, and the feasibility of combining a weak signal extraction with correlation function method on a system identification is reasoned, and the method is analyzed from practical point of view.
