摘    要:在对虚拟仪器动态测量系统做离散域分析的基础上,应用最小二乘法实现虚拟仪器动态测量系统参数辨识.鉴于应用最小二乘法系统参数辨识计算时存在矩阵求逆困难,不适宜于在线实时参数评估,探讨一种递推改进方法去弥补最小二乘法的不足,通过具体的虚拟仪器动态测量实例,验证所提议的改进方法的正确性和优越性.

关 键 词:虚拟仪器  动态测量  参数辨识  递推最小二乘法  虚拟仪器  动态测量  系统参数辨识  Virtual  Instrument  Measurement  System  Dynamic  Identification  验证  测量实例  改进方法  递推  参数评估  在线实时  矩阵求逆  存在  计算  乘法  最小  应用  域分析

Abstract:The virtual instrument dynamic measurement system was analysed and the least squares identification method was used in the process. Discussed a new recursive method to overcome the operation difficulty of the least squares identification method. According to a special example, the parameters of the recursive method were in a good agreement with the real ones, the validity of the proposed method was represented.
Keywords:virtual instrument  dynamic measurement  parameter identification  recursive least squares identificationmethod
