In v iew of the prob lem of correction of the end of ballistic trajectory o f mortar, this paper bu ilds a dynam ics model based on mi pulse control and ana lyzes the effect of mi pulse and tra jectory parameters on term inal correct ion ability and trajectory characteristic. The parameters include mi pulse numbers, forces, location position, rotating speed o f pills, working-tmi e of mi pu lse. The paper completes the smi ulation calculation w ith the model and arithmetics, draw s the curves of attack ang le in the correction progress. The resu lt show s that the warp is reduced effect ively by the mi pulse control and that themodel and arithmetic are suitable for smi ulation calculation and ana lysis under mi pulse contro.l Th is research offers academ ic reference for mi pulse control design o f term ina l correction pro jectile.
