文摘隐喻,是使用"是"、"成"等词把某事物比拟成同其有相似关系的另一事物的一种修辞表达。隐喻总是显性或隐性地包含着概念层表达式"X BE Y";其中,X和Y分属两个不同范畴。表达式"X BE Y"成为隐喻概念层表达式有两个主要理据:谓词BE能够进行外延—内涵性双重逻辑解读①,保证了表达式"X BE Y"既可在表面上利用Y的外延对X进行述说又可利用Y的内涵属性对X进行述说;其识解依赖人类常规关系认知范式,这种常规关系或知识结合语境限制因素解决了"X BE Y"中喻体Y部分属性的提取问题。

文摘The tracking problem for a class of differential inclusion systems is investigated. Using global sliding mode control approach, a tracking control is proposed such that the output of a differential inclusion system tracks the desired trajectory asymptotically.An extensive reaching law is proposed to achieve the chattering reduction. Finally, an example is given to illustrate the validity of the proposed design.
