摘要
本文根据薄膜热电偶传感器动态标定实验结果 ,研究了辨识一类非线性系统模型的方法 .文中采用 Hammerstein模型作为系统结构 ,在此基础上 ,对模型参数加以估计 .考虑到动态系统各环节之间的输入输出关系 ,进一步简化了 Hammerstein模型结构 ,以便运用简便的方法来估计模型参数 .通过对几组实验数据的仿真和检验 ,证明本文所采用的方法能够获得较好的辨识效果 .
According to the results of the experiment of dynamic measrue system, the method of identification for a type of non linear system is discussed and the Hammers tein model is used in this article. Since the relationship between the dynamic m easrue system input and output is paid attention to, the Hammerstein model is si mplified then, so as to apply simple resolution. It is proved to be able to obta in good result, by simulation and check with several sets of data.
