Under　the　conditions　of　small　batch,　there　are　many　problems　in　the　applications　of　statistical　process　control　(SPC),　which　has　limitation　in　the　course　of　modern　industry.　The　parameterσ　must　maintain　invariably　which　comes　from　its　supposition　process　white　noise　N　(0　σ),　or　else　the　control　chart　is　untenable.　This　paper　proposed　to　carry　on　the　quality　control　using　the　Kalman　filtering.　Using　the　Kalman　filtering　as　the　basic　theory　of　the　industry　quality　control　process　can　fully　reflect　the　content　of　control.　It　can　completely　eliminate　inadaptation　of　the　using　with　SPC　in　the　course　of　modern　industry　quality　control　process.　Through　the　example　research,　the　paper　indicates　that　the　Kalman　filtering　has　the　compatibility　of　the　quality　control　compared　to　SPC,　the　estimating　error　of　which　is　small.　©　2009　IEEE.
