CONTROL METHOD FOR THE MENISCUS OF A CONTINUOUS CASTING MOLD |
摘要 |
The inflow of liquid metal into a continuous casting mould is set by a closure device. A measured actual meniscus value is fed to a controller determining a closure device target position on the basis of the actual and a corresponding target value. The measured actual value is fed to a disturbance variable compensator. The target position/corrected target position or a corresponding actual value are further fed to the disturbance variable compensator which determines the disturbance variable compensation value. The disturbance variable compensator has a model of the continuous casting mold for determining an expected value. A number of oscillating compensators determine a frequency disturbance proportion. The sum of the frequency disturbance proportions corresponds to the disturbance variable compensation value. The disturbance variable compensator has a jump determiner, by which it determines the jump compensation value by integrating the difference. |
