基于黑板模型的智能控制结构

智能控制与传统控制机理的不同之处在于它直接利用了人的有关知识.智能控制包括两个方面的条件因素:一是要有足够的关于控制的知识;另一个是要建立适当的知识应用结构.本文将专家系统中的黑板模型引入智能控制的机理分析,并加以改进,成为一个适应性较广的智能控制结构.这种结构不仅包括了现有的各种智能控制形式,也适用于一些传统的控制方式.按照这种结构,还可以演绎出其它智能控制方式.本文最后给出了一个针对实际问题的智能控制系统设计实例.

INTELLIGENT CONTROL STRUCTURE BASED ON BLACKBOARD MODEL

The mechanism difference between intelligent control and traditional control lies in that the former has been utilizing directlyrelated knowlege of human being.The intelligent control has two aspects of conditional factors,i.e.,the requirement of sufficientknowlege about control and the necessity of establishing a proper structure of knowlege application.This paper introduces ablackboard model in expert system into the mechanism analysis of intelligent control.This model,after improvement,becomes anintelligent control structure with better adaptability,which not only contains various intelligent control fashions howavailable,but also is suitable to several traditional control fashions.At last,we present an actual example of intelligent control sys-tem design in connection with practical problem.
