关键词： NEUROFUZZY IDENTIFIER   INVERSE FUZZY RELATION   FEEDFORWARD CONTROLLER   FEEDBACK CONTROLLER WITH LEARNING CAPABILITY   STABILITY  

摘要： A new neurofuzzy controller design algorithm using a neurofuzzy identifier is proposed. The neurofuzzy identifier identifies a fuzzy system and is used for representing the relational degrees between the reference input and output fuzzy sets. From the calculation of possibility between the neurofuzzy identifier output and the fuzzified value of the desired output, a control input for the desired output can be extracted and used for construction of a feedforward controller. In order to increase the control performance, a feedback control architecture with learning capability is also proposed. A multilayer neural network controller with the initial weight values that are obtained from learning the proportional and derivative control action is trained by an error back-propagation learning algorithm with the neural identifier minimizing the feedback control error. Computer simulation results show that the proposed method is effective for fuzzy central of a system in the case that the initial fuzzy control rules are unknown, and the proposed feedback neurocontrol architecture is shown not only to enhance the control performances but also to satisfy the stability criterion.

关键词： RANGE ESTIMATION   FEATURE CORRESPONDENCE   OBSERVER DESIGN   MACHINE VISION  

摘要： In this paper we consider the problem of estimating the range information of features on an affine plane in R(3) by observing its image with the aid of a CCD camera, wherein we assume that the camera is undergoing a known motion. The features considered are points, lines and planar curves located on planar surfaces of static objects. The dynamics of the moving projections of the features on the image plane have been described as a suitable differential equation on an appropriate feature space. This dynamics is used to estimate feature parameters from which the range information is readily available. In this paper the proposed identification has been carried out via a newly introduced identifier based observer. Performance of the observer has been studied via simulation.

摘要： We present a new adaptive nonlinear control design which achieves a complete controller-identifier separation. This modularity is made possible by a strong input-to-state stability property of the new controller with respect to the parameter estimation error and its derivative as inputs. These inputs are independently guaranteed to be bounded by the identifier. The new design is more flexible than the Lyapunov-based design because the identifier can employ any standard update law gradient and least-squares, normalized and unnormalized. A key ingredient in the identifier design and convergence analysis is a nonlinear extension of the well-known linear swapping lemma.

摘要： 硬件扬声器静音新法我发现了一种使扬声器不发声的新方法,这种方法简便易行,无须再购买一个新开关。我利用计算机的键盘锁开关,这是因为我用计算机时,没有必要锁上键盘。只要将连接扬声器的导线从中间断开,再将两个断点分别接到键盘锁开关的两端就行了。使用这种方法,你既无须在机箱上打洞,又无须再安装一个新开关。如果你觉得孩子玩计算机游戏时太吵闹,你只要锁上键盘并收藏好键盘锁的钥匙就可以万事大吉了!Sylvain RodrigueMirdlel,Quebec。

摘要： 基于线列的CCD技术已被成功地用于发展一种自动货币阅读器/比较器(ACR/C)系统。这种ACR/C系统是为提供一种货币跟踪方法而设计的,它将专门用于在有组织犯罪和毒品车辆通行环境中跟踪美国货币,因为这些环境中的一些非法交易和洗钱活动会涉及大量现金。利用面额、序号及连续年份的组合,便能够对美国流通纸币进行独特的鉴别。ACR/C系统是利用一个专用传送装置、一个固定线列以及光学字符识别(OCR)技术进行这种鉴别的,它能以每秒5张纸币的速度处理纸币。这样,便可以给大量货币“加上符号”(用该系统阅读并将它们的标识符储存起来),然后使它们在各种各样的犯罪网络内流通。以后,便可以用该系统阅读被没收的纸币,并将它们同从“加符号的”数据中取出的已知标识符集进行比较,以提供犯罪活动的线索。 借助这种ACR/C系统,执法机构便能够在不实际注明货币的情况下,有效地鉴别货币。这为能逐一追踪一张纸币提供了一种不可发现的手段,并使得记录保持变得更加方便,从而给法院提供证据。此外,如果将多个系统连同中央数据库一起使用,则该系统还可以用来从地理上跟踪货币。
