Design And Research For Horizontal Continuous Casting Intelligent Control System

Continuous Casting steel as a great technology of the iron and steel enterprise in succession, is the important link of linking up smelting and rolled steel in the flow of producing of steel. Because have a series of generally acknowledged merits, such as high efficiency, high quality, high lumber recovery with low costs,etc. to cast steel in succession , Every country in the world ,which is developping energetically , cast and liken improving to optimizing for the structure of steel factory,strengthen the key link that the market fought for ability and increasing economic efficiency as the central link. The level suitable for the medium and small-scale steel factory casts technology in succession in the conduct is continuous casting , which for its production variety, short run, and relatively high to cast steel unique advantage pay attention to products,etc. But the level casing steel in succession the system is a complicated control system, which have the characteristics of the variable,strong coupling more interfering, parameter easy change more. Especially the base machine require the precision of transmission of the device to expect very much to it,and its control is more difficulty of heavy degree systematically in succession than arc casting, so resulted in the popularity and application of technology in succession of horizontal continous casting getting influence. The development application study that the iron and steel enterprise of our country's horizontal continous casting technology to the level in succession is still in primary stage at present, so it has realistic significance ,which to further investigation in the level horizontal continous casting control system .The author analyses and researches carefully the question that now the domestic horizontal continous casting control system through surveying and studing on the spot. This paper aims at horizontal continous casting and base machine control by the drives of machine, to design servo to transfer systematic speed synchronous motor permanent magnetism PWM in succession to level. Since the uncertain factors,such as the parameters exchange of servo system ,load perturbation and exchange motor oneself and the controled target into the seriously non-linear, better couplings,etc. It is unable to reach the satisfied control result that routinePID controls, design the control scheme of Fuzzy-PID. Have proposed one by controlling Fuzzy-PID which adjusts PID parameter and control algorithms fuzzily according to the dynamic characteristic and behavior of the system in the course of controlling. Have designed Fuzzy-PID controller, and carried on emulation under the MATLAB environment, has been compared with traditional PID, then proves its superiority design competence cast the monitoring system even with the MCGS configuration software.
