摘要
针对测量中单输入单输出线性系统的动态建模问题,通过计算机数字仿真,对现有的几种定阶方法进行了研究、分析,比较了它们在不同信噪比、不同数据长度、不同模型情况下模型定阶的可靠性、等价性和选择原则,并得到了一些重要的结论。
Considering the dynamic modeling of single input single output linear system in measurement, various criteria for the model order determination are studied. Their reliability, equality and select rule are analysised and compared in different conditions by computer digital sisimulation test. Some important conclusions are obtained.
