在汽车上使用的新技术中,有一种被称之为模糊控制技术。那么,什么是模糊控制?汽车上为什么要使用模糊控制技术呢? 我们知道,计算机处理精确信息达到无与伦比的程度,但是,人轻而易举就能做到的许多事情它却做不了。这是为什么呢?原来,人具有识别模糊事物、运用模糊概念的能力。 世界上许多东西是不能用精确的数学模型来表达的。人的语言中就有大量的诸如“大概”、“差不多”、“稍高”、“偏低”之类的词语。事实上,处理许多事情用模糊的方式比用精确的方式更有效。例如
One of the new technologies used in cars is called fuzzy control. So what is fuzzy control? Why is fuzzy control technology used in cars? We know that computers handle accurate information to an unparalleled level, but many things that people can do with ease can not. Why is this? Originally, people had the ability to identify vague things and apply vague concepts. Many things in the world can not be expressed in precise mathematical models. There are a lot of words in human language such as “about”, “about the same”, “slightly higher” and “lower”. In fact, it’s more effective to deal with many things in a vague way than in a precise one. E.g
