智能控制是自动控制发展的高级阶段,是人工智能、控制论、系统论和信息论等多种学科的高度综合 与集成,是一门新的交叉前沿学科。从广义上讲,智能控制是研究对复杂的不确定性被控对象(过程)采 用人工智能的方法有效地克服系统的不确定性,使系统从无序到期望的有序状态转移的方法及其规律 智能控制已经出现了相当长的一段时间,并且取得了初步的应用成果

Fuzzy control does not exist as an isolated topic devoid of relationships to other fields, and it is important to understand how it relates to these other fields in order to strengthen your understanding of it. We have emphasized that fuzzy control has its foundations in conventional control and that there are many relationships to techniques, ideas, and methodologi there. Fuzzy control is also an\intelligent control\technique

The design process for fuzzy controllers that is based on the use of heuristic information from human experts has found success in many industrial applications. Moreover, the approach to constructing fuzzy controllers via numerical input-output data is increasingly finding use
