从模型取状态的离散模型参考自适应控制系统设计及应用

The Design and Application for Discrete MRACS of Taking State from Model

本文基于波波夫超稳定理论,提出了一种离散模型参考自适应控制系统的设计方案。这种方案利用连续系统从模型取状态的设计思想直接取模型的状态作为综合自适应算法的输入信号之一,而不是利用对象的状态,从而减少了输出端扰动对适应过程的影响。文中分两种情况给出了两种控制器结构及相应的算法,最后示出了在调速系统上的实验结果。

Based on Popov hyperstable theory,this paper presents a kind of design scheme for discrete MRACS.The scheme makes use of the state of model as control signal needed in adaptive algorithms.The scheme is able to dec-rese the influence of disturbance coming from output.The paper presents two kinds of algorithms for two kinds of controller structure and the paper gives the result of experiment on DC motor speed control system.
