Zastosowanie elementów logiki rozmytej do oceny układów elektromaszynowych

Owing to a great variety of industrial electro-machine systems, it becomes more and more crucial to assess correctly electro-machine systems offered by their suppliers. It has been proved in this paper that by assessing systems offered to them exclusively on the basis of bivalent rules, purchasers are likely to incur economical losses. It is essential to apply elements of fuzzy (or multivalent) logics while performing such on assessment. With this purpose the notion of Hamming distance, applied in the theory of mathematical sets has been used in the easiest possible way. The Hamming distance, which defines an agreed distance between two sets of certain quantities, turned out to be useful for proposing a way of assessment of offered electro-machine systems. Considering same characteristics of electro-machine systems as quantities included in sets defined by a Hamming distance a theoretical basis of such an assessment can be obtained. The paper presents a simple and interesting geometric interpretation of the abovementioned solutions. It also reveals a method of assessment and reciprocal comparison of offered electro-machine systems.
