模糊系统的函数逼近特性研究

模糊系统的函数逼近理论是模糊系统理论的一个重要支柱。自从 Wang( 1 992 )首先基于一类特殊模糊系统 ,提出这一理论以来 ,很多学者作了进一步的研究。本文提出了一类较为一般的模糊系统 ,基于有限覆盖定理 ,对这一理论 ,提出了一种新的并且简单的证明方法。最后 ,通过对一般模糊系统的分析研究 ,指出了模糊系统在函数逼近方面的本质特性及局限性。

基于TS模型的一类模糊控制器设计

本文基于 Ｔ Ｓ模型，提出了一类模糊 Ｐ Ｉ Ｄ（ Ｔ Ｓ－ Ｐ Ｉ Ｄ）控制器的设计。这类模糊 Ｐ Ｉ Ｄ控制器前件采用模糊推理，后件采用 Ｐ Ｉ Ｄ算法，是一种真正意义下的复合控制器，具有较强的应用潜力。仿真结果表明了这类模糊 Ｐ Ｉ Ｄ控制器的优越性。

TREATMENT OF UPPER RESPIRATORY TRACT INFECTION BY QIGONG——Selected from A Practical English-Chinese Library of Traditional Chinese Medicine

An upper respiratory tract infection is acatarrhal inflammation of the upperrespiratory tract caused by viruses or bacte-ria.The chief clinical manifestations arestuffy nose,nasal discharge,sneezing,coughing and sore-throat,as well as aver-sion to wind,fever and headache.Tradi-tional Chinese medicine calls it“gan mao(common cold)”.

数字助听设备的多通道系统综述

本文主要介绍了数字助听设备的多通道系统的分类以及实现方法。目前,数字助听设备大多数都是基于多通道的结构来实现,因此,多通道的系统结构的实现方法在数字助听设备的设计中占有重要作用。本文介绍了多通道系统的分类,并对一些常用的方法进行了分析分析和综述。助听设备可以对具有听力损失的人群进行有针对性的响度补偿,从而,改善使用者对外界声音的感知能力。传统的助听器都需要根据使用者的具体情况由专业人士进行验配,以获得更好的使用效果。由于助听器的验配过程较为复杂,在一定程度上影响了助听器的佩戴和使用率。
