    摘要: A method for controlling furnace temperature of a fired heating furnace is disclosed, comprising: measuring furnace temperatures to obtain furnace temperature feedback values; calculating the differences between furnace temperature setting values and the furnace temperature feedback values as discrepancy values DV1, in accordance with the furnace temperature feedback values and the furnace temperature setting value; calculating the differences between the furnace temperature setting values and the furnace temperature feedback values in a unit time, i.e., the gradient of furnace temperature change values, as discrepancy values DV2; obtaining a speed V of a fired heater machine set from a speed adjuster of the fired heater machine set, and obtaining a first multiple feed forward output components FFV in accordance with the speed V of the machine set (V); obtaining a second multiple feed forward output components FFT in accordance with the differences between the furnace temperature setting values and the furnace temperature feedback values, i.e., the discrepancy values DV1; looking up a PID control parameter in accordance with the discrepancy values DV1 and DV2, based on fuzzy control rule, and creating an adjusting control parameter OP1 in accordance with the PID control parameter; controlling a valve for regulating coal gas flow and a valve for regulating air flow by combining the adjusting control parameter OP1 with the first multiple feed forward components FFV and the second multiple feed forward components FFT as a final control output value.
