Research on On-Line Identification Based Dynamic Hunting Extremum Control Strategy

本文介绍一种非线性环节采用折线近似表示的Ｈａｍｍｅｒｓｔｅｉｎ模型系统的参数辨识方法；针对非线性环节呈极值特性的情况，研究一种根据在线辨识得到的线性动态环节的参数估计值进行极值系统动态优化的控制方法，仿真结果验证了该方法的有效性．

This paper briefly gives a parameter estimation method of discrete Hammerstein model based on the piece-wise linear expression of nonlinear part. For the extremum nonlinear properties,a dynamic hunting control strategy with on-line estimated values of linear parameters is presented. A simulation result shows the effectiveness of the algorithm.
