Disclosed is a small perturbation reversal control method for kiln furnace which comprises determining the real requirement of the kiln manufacturing process and burning behavior, during the procedure of fire change which is less than 35 seconds, pre-treating the fuel and the proportion of combustion air quantity, during the procedure from natural gas cut-off to opening, increasing regenerator secondary air amount by a predetermined proportion, when the natural gas is opened, reducing natural gas incoming by a predetermined proportion, elevating gradually to a set value, reducing the secondary air amount of the multiple inputs step by step to the original set point, thus stabilizing the kiln furnace pressure within a dozen of seconds, which is beneficial for the stabilization for the melting tank vitreous body level.
