PURPOSE:To improve the reliability of a simulator, by controlling a plant based on a simulated value, while performing the simulation of the plant time by time. CONSTITUTION:In a converter 1, as steel making reactions, reactions such as dephosphorization, denitration, desulfurization, and decarburization are carried out. Further, a reaction simulator operates a reaction equation at a prescribed time interval and outputs the result of operation to a controller 5. The controller 5 operates the supply amount of oxygen and of slag making agent and outputs the result to the simulator 4 and regulators 2, 3. The simulator 4 operates the next states by using an output value of the controller 5. When one stage of steel-making is finished, the molten steel is discharged and the content of steel is analyzed at an analyzer 7 inputted from a sensor 12 and the result of analysis 13 is outputted to a model correcting device 6. The device 6 obtains error of the operation of the simulator and corrects 11 the mathematical model of the simulator. |
