Abstract

Abstract:

　A matching design of exact model was presented for the discrete time nonlinear system described by a Hammerstein model .The Hammerstein model consists of a memory -less nonlinear function represented by the odd -order polynomial and a linear time invariant (LTI) subsy stems in cascade connection .The controller structure of the exact model matching was proposed, and self -adaptive control algorithms were deduced for the Hammerstein model .The effectiveness of the pro posed scheme is validated in numerical simulation way .

Key words: Adaptive control, , Hammerstein model, , Exact model matching, , Nonlinear system

摘要： 对于Hammerstein 模型描述的一类离散时间非线性系统, 提出一个精确模型匹配设计。该Hammer stein 模型是由一个用奇数阶多项式表示的无记忆非线性环节和一个线性时不变子系统级联组成。对于此模型提出了精确模型匹配控制器的结构, 并推导了自适应控制律。最后, 通过数值仿真证明了该设计方案的有效性。
