Abstract
The authors have off ered the algorithm of dual-mode control with the simultaneous identifi cation of the change model of oxygen expense intensity for blowing – carbon dioxide content change in exit gases of steel converter melting and the correction of oxygen expense during the fi nal period of melting. Such a unifi cation was reached at the expense of control action of a step type in the given point of time and its fi xation on the time interval of a transient process from this action, registration of the data of control and output actions at the time interval of a transient process, calculation by these data of model coeffi cient and the size of control action with the use of the received coeffi cient assessment, realization of control actions on the next control interval. The article also presents the results of effi ciency assessment of the proposed control algorithm: the indicator of “smoothness” of the time series of carbon control in metal in the critical point and the percentage of hits of carbon content in steel in the set interval at the turn-down of the converter.
