Definitions
- the invention relates to a method for measuring and / or regulating the Flatness of strips during rolling.
- the length distribution of the rolled sheet by means a Planheitsmeßsystems to determine (see Figure 1).
- the different Types of errors - e.g. Center waves, edge waves, quarter waves or unevennesses of higher order - are determined by a mathematical Analysis of the measured length distribution determined to specifically the to use suitable actuators for error correction.
- one-sided edge waves on the left or right side of the band are described by the coefficients a 1 and a 3 .
- the coefficients a 2 and a 4 describe either symmetrical center waves or symmetrical edge waves on the left and right sides of the band.
- the coefficients a 1 and a 3 or a 2 and a 4 thus contain common information components.
- the manipulated variables of the work roll bending for the compensation of the components a 2 and a 4 and the hydraulic positions on the operator and drive side (panning) are used to eliminate the error components a 1 and a 3 .
- the coefficients a 1 and a 3 are used for the pivoting
- the coef fi cients a 2 and a 4 are used as the controlled variable for the bending.
- the axial displacement of the work rolls is used primarily for presetting the roll gap contour and only occasionally within of the control loop in combination with the bend to correct the Quarter wave.
- the selective multi - zone cooling of Work rolls allow the correction of the flatness errors higher order.
- Such a regulation is for example from the German Patent application DE 197 58 466 A1 known.
- This control system can meet the increasing quality requirements to the flatness do not do justice, since the flatness regulation only after relatively high time reaches its target curve. This has the consequence that First, a large tape length must be taken into account, whose Flatness lies outside the tolerance. Often, however, the setpoint curve not at all, but achieved only in approximation, so that large marginal or Center waves can arise.
- the components a 0 , a 1 , a 2 , a 3 and a 4 influence one another and do not take into account the dead times, ie they are not compensated.
- the actuator characteristics (influence functions) are calculated and assumed to be constant only once per band since iterative model equations are used for the calculation.
- the Smith predicator is a classic one Multi-variable controller (PID controller) integrated. It lacks a dynamic Optimization with prediction beyond the dead time Controlled variable course. Here is a rule predicted, the occurs immediately after the dead time in the first scanning step.
- the invention is therefore based on the object to provide a method that measuring and / or regulating the flatness of a band reliable when rolling.
- the invention is based on the idea, the flatness control in the prior art by an orthogonal model-based Multi-size flatness control system with registration of flatness and their decomposition into orthogonal components to improve and the Stability of the control loop through consideration of measuring systems with time-variant sampling time using an IMC (Internal Model Control) approach is improved with event-triggered scanning elements.
- IMC Internal Model Control
- the multi-size flatness control system has a determination the manipulated variables by means of a dynamic online optimization under consideration of manipulated variables restrictions on and a prediction of the controlled variables (flatness values), which result in a dynamic optimization is included. The prediction of the controlled variables goes beyond the Dead time out.
- the model-based predictive approach becomes a Prediction of the controlled variables from the first sampling step to the dead time used up to a prediction horizon. This will become everyone Time optimal manipulated variables calculated, even if the time constants the individual actuators are very different. This information advantageously also participate in dynamic optimization one.
- the components can be compared with values which provides an online-capable model of the plant.
- the resulting Difference can serve as a control variable and then with the in unabracee Components decomposed Sollplanheitskurve be compared.
- the resulting control difference can be achieved via optimal decoupling fed to a multi-variable controller.
- Dead time taken into account by the Internal Model Control (IMC) approach can be. This can shorten the settling time and the tape length be reduced, which is outside the tolerance range.
- IMC Internal Model Control
- the inventive method further allows the consideration the change of rolling force, thermal crowning and the incoming tape properties at each time step by a Feedforward.
- the decomposition of the components may advantageously be orthogonal Polynomials, for example with the help of Chebyshev polynomials or Gram polynomials, as described in W.H. Press, S.A. Teukolsky, W.T. Vetterling, B.P. Flannery: Numerical Recipes at C, Cambridge University Press (1992) or A. Ralston, P. Rabinowitz: A first course in numerical analysis, International series in pure applied mathematics, McGraw-Hill (1978).
- the flatness of the leaking sheet can be achieved by bending, swiveling and axial displacement of the rolls and by selective multi-zone cooling to be influenced.
- the individual manipulated variables can help with a multivariable controller from the above-described control difference be determined. In this case, the influence of the rolling force, the incoming Band properties and thermal crowning by a Feedforward control can be compensated.
- the flatness deviation by means of a measuring system determined and then into orthogonal (independent) components disassembled.
- the components are compared with values that a online-enabled model of the plant supplies.
- the resulting difference is called Controlled variable used.
- This is then used in independent Components decomposed Sollplanheitskurve and the resulting Control difference is a multi-variable controller, consisting of an online-enabled Model and a dynamic optimization involving Manipulated variable restrictions and predicted control variable course, fed.
- variable Sampling time is an event-triggered sampling system with one with two Abtasthaltegliedem cooperating event generator provided.
- the flatness of the leaking sheet is determined by bending, swiveling and Axial displacement of the rollers as well as through selective multi-zone cooling affected.
- the individual manipulated variables are calculated using a multivariable controller determined from the above-described control difference. It is the Influence of rolling force, incoming strip properties and thermal Camber compensated by a feedforward control.
