摘要
Hammerstein模型是一类具有特定结构的典型非线性模型,由静态非线性环节和动态线性环节串联而成,能较好地反映过程特征的特点,可以描述一大类非线性过程.本文结合Hammerstein模型辨识的基本过程和特点,从Hammerstein模型中间变量不可测量的角度出发,首先按静态非线性环节与动态线性环节同步辨识法和分步辨识法综述了Hammerstein模型的相关理论和方法;然后,分析了现有的基于Hammerstein模型的控制系统设计方案;最后对Hammerstein系统未来可能的研究提出若干看法.
Hammerstein model is a typical nonlinear model consisting of the cascade structure of a static nonlinear element followed by a dynamic linear element. It represents a wide class of nonlinear processes. Considering immeasurable intermediate variables in the Hammerstein model, we survey the relevant theories and the synchronous method as well as the separate step method for identifying the static nonlinear element and the dynamic linear element. Then, we review the existing control system design schemes based on Hammerstein model. Finally, several opinions of the future research are given.
