Processing Method for Complex Characteristics of Electromagnetic Devices

This article discusses the development of a method for processing the integral characteristics of electromagnetic devices, which are complex functions. In cases where a complex function has a dependence on a nonmonotonic function, its hyste-resis character is manifested. Such functions are difficult and sometimes impossible, to be processed by numerical dimensional-ity reduction methods (for example, the method of principal components, Wavelet transform). The developed method makes it possible to represent integral functions in an “expanded” form, i.e. get rid of back loops due to the monotonic representation of the nested function. The performed analysis of the dynamic characteristics of electromagnets shows that such processing does not result in the loss of important information, and the charac-teristics can later be transferred to the space of principal components. In this space, characteristics that have already been pro-cessed form a structured dependence and can be separated into clusters.
