A Rtal-Time Correlative Identification System

本文介绍一种应用8031单片机系统和Apple-Ⅲ微型计算机组成的实时相关辨识系统的构成和工作原理。该系统采用逆重复二电平伪随机序列作为输入激励信号,具有实时测试和跟踪功能,可以获得被测系统的脉冲响应、频率特性及传递函数等数据。

The paper introduces the structure and the principle of a real-time correlative identification system implemented by 8031 single chip microprocessor and Apple-Ⅱ microcomputer. The system uses the reverse repetitive two-level pseudorandom sequences as the input excitation signal, and offers the functions of the real-time test and track. It can be used to obtain the impuls response, the frequency characteristics and the transfer function of the measured system.
