A Self-adaptive Play Model with Input-dependent Shape Func-tions for Hysteresis Loss of Electromagnetic Devices.

摘要

Play models are capable of representing minor hysteresis loops of a silicon steel sheet. This paper presents an identification method which can automatically detect the number of play hysterons needed for the simulation. Single sheet tester is applied to get the symmetric B-H loops and first-order reversal curves to identify the play models. Two types of play models are employed in this work. Simulated minor loops, representation of errors, and symmetric B-H loops are presented to verify the accuracy of the proposed method.
