How to use MILS to generate an LS model

Overview of MILS interface

MILS is an identification tool composed of four panels. Each panel corresponds to a step required in the identification of an LS model representing the hysteretical behavior of a ferromagnetic steel sheet.

The purpose of each panel or step is summarized below:
  • Step 1 - Static Identification panel: uses low-frequency magnetic measurements to evaluate the static component of the LS model.
  • Step 2 - Dynamic Identification panel: uses magnetic measurements performed at several frequencies to evaluate the dynamic component of the LS model.
  • Step 3 - Overall Verification panel: an optional step used to validate the model issued from the static and dynamic identification steps.
  • Step 4 - Model generation panel: creates a .mils file containing the LS model identified. This file is compatible with Altair FluxTM and may be easily imported in that software to describe magnetic regions. In this step, the user may also generate and export a report of the model identification (in .txt format) and a table (in Microsoft Excel .xls format), providing iron loss estimations computed with the LS model.

The user may switch between identification steps by clicking on the buttons on the bottom right corner of each panel in MILS. The diagram in Figure 1 shows how to navigate throughout the interface:
