摘　　要：用伪随机二进制序列进行相关分析是辨识系统脉冲响应函数的有效方法。给出一种用伪随机m序列作为输入信号,用LabVIEW实现信号采集的辨识系统平台,其中m序列基于FPGA生成,改变少数参数就可以对序列长度、周期等进行了调整。最后,给出了两个辨识实例。Correlation analysis,using pseudo-random binary sequence as input,is an effective method to identify the impulse response of control.In this paper,an identification system platform was present,which used pseudo-random m sequence as the input signal and LabVIEW for signal acquisition.The pseudo-random m sequence generated based on FPGA,so the length and cycle of the sequence could be adjusted easily.Finally,two examples of identification were given.
