摘要： The invention relates to a method for guiding a strip between two opposite coils of a device which comprises a position sensor for determining the position of the strip between the coils. The first coil is impinged upon with a first current and the second coil is impinged upon with a second current if the strip deviates from the desired position.

摘要： According to the invention, the thickness, traction forces and flatness is controlled by means of a single control device as part of an integrated, model-predictive thickness, traction and flatness control operation. The integrated control device takes into account the influence the adjustment of the control variables has on the thickness, the traction force and the flatness of the rolled strip and optimises the modifications of the control variable in such a way that a selected quality of the thickness and the flatness control is obtained. The quality of the thickness and the quality of the flatness control, which are weighted differently, can effect the quality function of the control device. The use of the integrated control device improves the performance and the stability of the control device in relation to the control devices which are arranged in a separate manner from each other.

摘要： The invention relates to a strip coating method according to which the strip is guided through two opposite coils of a strip guiding device upstream or downstream of a coating device. Said strip guiding device comprises a position sensor for determining the position of the strip between the coils, current suppliers for the coils and a layer thickness sensor for determining the layer thickness of the coating applied to the strip. The inventive method comprises the following steps: determining a desired layer thickness profile, determining an actual layer thickness profile using the layer thickness sensor, determining a layer thickness control variable by comparing the actual layer thickness profile with the desired layer thickness profile, determining a desired position value for the strip position between the opposite coils using a higher order layer thickness controller whose input signal is the layer thickness control variable, determining an actual position value of the strip between the opposite coils using the position sensor, determining a position control difference by comparing the actual position value with the desired position value, impinging at least one of the coils with current, the current being adjusted in accordance with the output signal of a position controller whose input signal is the position control variable.

摘要： The invention relates to a method for determining the surface profile of a coated strip (5) which is transported through a device by a device and influenced by least one actuator, in addition to a method for regulating control variables for said process. Distance measurements are carried out in an offset manner and in relation to the direction in which the strip run, involving the following steps: the distance between the sensor (8) and the surface of the strip (5) is determined for at least one measuring point; the characterising values of a surface profile equation are calculated from the determined distance values by means of a switched Kalman filter; the surface profile of a coated strip guided through a device is determined in a precise manner and the adjustable variables are regulated in a precise manner.
