Aiming　at　the　problems　of　inaccurate　model,　coupling　of　identification　parameters,　and　low　identification　accuracy　in　the　identification　of　permanent　magnet　synchronous　linear　motor　(PMSLM)　mechanical　parameters,　a　mechanical　parameter　identification　algorithm　based　on　transmission　model　reconstruction　was　proposed　in　this　paper.　First,　an　extended　state　observer　was　established　based　on　the　reconstruction　model　to　obtain　the　coupling　information　of　the　mover　mass　and　friction　force,　electromagnetic　thrust　and　initial　value　of　mass　identification.　Secondly,　in　order　to　eliminate　this　coupling,　a　two-stage　mover　mass　decoupling　identification　strategy　was　proposed.　Thirdly,　according　to　the　friction　characteristics　of　PMSLM,　a　friction　force　model　that　comprehensively　considers　the　effects　of　velocity　and　acceleration　was　constructed　to　describe　the　real　friction　force　more　accurately.　Finally,　a　control　system　based　on　the　mechanical　parameter　identification　algorithm　was　built,　and　the　effectiveness　of　the　identification　algorithm　proposed　in　this　paper　is　proved　by　simulation　and　experimental　verification.　©2024　Chin.Soc.for　Elec.Eng.　1597.
