本文从动态辨识技术实际应用的角度出发,利用计算机数字仿真等技术,分析比较了COR—LS法在线辨识中相关函数最大时间间隔M_o,输入p·r·b·s的参数N和采样次数T_m三者对辨识结果的影响。并由此提出一些建议,供在实际应用中参考。其中关于输入信号和采样周期上的参数选择建议,也适用于其它辨识方法。
Based on the practical application of dynamic identification technology, this paper analyzes and compares the maximum time interval M_o of correlation function in online identification of COR-LS method by using computer numerical simulation techniques. The parameter N of input p · r · b · s and the number of sampling times T_m The impact of the three on the identification results. And put forward some suggestions for reference in the practical application. Among them, the suggestion of parameter selection on input signal and sampling period also applies to other identification methods.
