Claim:
1. A control device of a coal pulverizer which pulverizes coal by the coal pulverizer and estimates coal output by which the pulverized coal is output to a boiler, the control device comprising: a main operation circuit configured to calculate a command signal associated with a coal feed rate on the basis of detection data from a boiler or a power generator connected to the boiler; and an additional control unit configured to calculate a deviation between a standard coal output pattern preset in the coal pulverizer and a current coal output pattern of the coal pulverizing operation, and to generate a correction signal based on the deviation, the correction signal being used to correct the command signal, wherein the additional control unit is configured to send the correction signal to the main operation circuit during the coal pulverizing operation, wherein the correction signal is added to the command signal so as to correct the command signal, and wherein the additional control unit comprises a coal output estimation unit configured to estimate the coal output of pulverized coal by using at least any of detection data from the coal pulverizer, detection data from the boiler, and detection data from the power generator.
