Bicriteria Optimization of Technological Parameters in Algorithm for Designing Magnetic Composites

Abstract

A novel algorithm for designing values of technological parameters for production of soft magnetic composites (SMC) has been created. These parameters are hardening temperature T and compaction pressure p. They enable us to optimize power losses and induction. The advantage of the presented algorithm consists in bicriteria optimization. The crucial role played by the presented algorithm is the scaling and pseudo-state equation. On this basis mathematical models of power losses and induction have been created. The model parameters have been calculated on the basis of the power loss characteristics and hysteresis loops. The created optimization system has been applied to specimens of Somaloy 500. The obtained output consists of a finite set of feasible solutions.In order to select a unique solution an additional criterion has been formulated.
