【Abstract】 The blast furnace blower, which sends wind to the blast furnace, is the crucial and complex equipment in metallurgical enterprise. So it is necessary to design a computer control system to insure that the blast furnace blower can work steadily, efficiently and safely. In this paper, the design of both the software and the hardware of the computer control system for the blast furnace blower are discussed explicitly. According to the characteristics of the blast furnace blower, further and thorough research on the control structure and algorithm is also achieved.Distribute Control System (DCS) is widely used in modern industrial process control field. At the beginning of this paper, the basic structure and features of the Distribute Control System are introduced. In terms of the control object and the principles of the Blast Furnace Blower, the structure and the overall design ideals of the compute control system are proposed. Then, the realizations of every control function in this compute control system are illustrated in details. Meanwhile, we focus our study on the principle and realization of the optimal control. Finally, the semi-physical simulation method and facture-debugging plan of this computer control system are presented.The computer control system of the blast furnace blower, which is designed in this paper, has already been put into use in the Bao Tou Steel Group. A steady control system and satisfactory control effect are obtained finally.更多还原
