研究了由静态非线性单元串联线性动态部分组成的Hammerstein模型在描述非线性化学过程动力学方面的应用。对不同的Hammerstein模型参数识别方法进行了测试。该方法已应用于模拟精馏塔的识别和热交换器的实验过程。结果表明，hammerstein型模型比线性模型能更好地表征这一过程的动力学特性。
The utility of the Hammerstein model, which is composed of a static nonlinear element in series with a linear dynamic part, was investigated to represent the dynamics of nonlinear chemical processes. Different methods to identify the parameters of Hammerstein models were tested. The methods were applied to the identification of simulated distillation columns and to an experimental heat exchanger process. The results show that the dynamics of such processes can be better represented by Hammerstein-type models than by linear models.
