Publisher description
Original publisher: [Washington, DC : National Aeronautics and Space Administration, 1992?] OCLC Number: (OCoLC)234294185 Subject: Space robotics. Excerpt: ... Large Positive AND the rate of error change is Large Positive THEN the control input should be Large Negative. Even though the qualitative linguistic term defining errer and error change is the same ( Large Positive ) the membership value associated with both of the states may differ. With the concepts used to develop a rule presented and the foregone conclusion that a fuzzy logic controller requires more than one rule to accomplish any reasonable task, a brief discussion of the techniques used to process the rule base follows. The rule base is simply all of the rules created to perform a particular task. Given the states of one such particular task, it is likely that some of the rules will be appropriate to the conditions presented and others will not. The rules that are inappropriate are discarded by the use of the Logic Product and the others are combined using the Logic Sum. The result of this combination of rules is a weighted area. By finding the Center of Gravity of this area a single numeric value results. This value is the final fuzzy inference and is a quanfized value. Dequantizing this fuzzy inference results in the final control input. With this brief overview complete, the reader may proceed further where a more detailed description of fuzzy logic control and its applications to various dynamic systems is presented
