摘要
本文把多值逻辑引入专家系统中的知识表示 ,着重就模糊规则向多值规则的转换 ,二值规则和多值规则的混合表示 ,二值逻辑向多值逻辑的转换 ,基于不同算子多值规则间的相互转换 ,以及采用管道结构从根本上解决专家系统中规则匹配速度慢等问题进行了研究 ,并首次将多值规则表示的知识用于电液位置伺服系统自适应律中的参数优化 ,进一步提高了控制器的性能 .
In this paper we use multiple valued logic (MVL) to express the knowledge in expert systems and deal with the uncertainties in nature.The extraction of MVL rules from fuzzy rules,the mixed expression of binary and MVL,the transition from binary logic to MVL,the transition between MVL rules based on different operators,and using pipelining to accelerate the matching of rule based expert systems are proposed.The knowledge expressed in MVL is used to optimize the parameter in the adaptive algorithm of electro hydraulic servo systems for the first time.Parameter optimization further improves the control performances of the adaptive controller.
