Fuzzy Controller Design

The direct trial method of designing fuzzy controllers is discussed and a performance-model reference method is presented.
On the basis of reviewing the maxi-min inference composition method, the methods of implementing fuzzy algorithm by means of logic circuits and increasing system performance by means of additional precision-regulated controller are given. To counteract the information-deficiency parasitizing the maxi-min method, the design method of using fuzzy numbers and interpolation principles is devised.
Transforming the performance indices into a performance model, applying the fuzzy theory to the identification of fuzzy-number model of the object, and computer implementation of fuzzy algorithms yield a performance-model-reference design method.
