Expert system for electric drive design

The problem of electric drive design concerns the multi-criteria non-linear problems having a number of solutions. In daily practice the search of optimum solution bases a great deal on the designer intuition and experience. Therefore, multiple obtained results have a low degree of equipment use, unwarranted complexity, or excessive cost. Proposed approach is devoted to implementation of the novel expert system into the design stages concerned the work with databases of the drive components. Examples of effective algorithms are given to choose an optimum ratio of electrical and mechanical components. The soft tool is developed to generate and edit structured query language sentences, to extract information from databases, as well as to suit multitude sets for particular applications.
