The invention discloses a flying crank shears control method with head and tail shearing compensation. The method comprises: after an electric current loop acquires output from a flying shears model machine, acquiring additional quantity for shearing a head part and additional quantity for shearing a tail part through an electric current loop via a site terminal; calculating the additional quantity for shearing the head part and the additional quantity for shearing the tail part respectively through an addition module and a subtraction module; exteriorly acquiring a select order for shearing the head and tail, and carrying out the calculation in turn through a numerical value conversion module, a division module and a coefficient calculating module in the electric current loop; acquiring aleading coefficient for shearing the head part and a lag coefficient for shearing the tail part, judging whether the coefficients are beyond preset limits, and adopting preset limit values if the coefficients exceed the preset limits; and outputting the processed results to a converter device through the electric current loop and continuing to control the flying shears to work.
