  • This speed control loop i.2 of the drive motor Mi associated with the clamping point i ( K i ) is subordinated to this register control loop.
  • the very small equivalent time constant of the current loop underlying the speed control loop is negligible.

  • the controlled variables namely, in the example, the partial register errors Y * / 13 and Y * / 1 i and the tensile force F i -1, i , are dependent on one another by the structure of the controlled system, ie coupled together. If, for example, a setpoint change F i -1, i , w is made, then the intervention of the tension controller 2.1 is connected to a speed control of the nip 2 ( K 2 ) and calls a partial register error Y * / 12, thus partial register error Y * / 13 and Y * / 1 i .

  • a partial register error to be regulated and a track traction to be controlled need not be in the same track section.
  • the multi-variable controlled system can be decoupled with the aid of the theory of multi-variable control, in the case of two controlled variables especially according to [Föl 88]. Without decoupling measures, the multi-variable control would be unstable. In particular, the multi-variable control is to be designed so that the web tensile forces and the partial register errors are decoupled from each other by corresponding setpoints in the control-technical sense.
  • velocities of nips located in front of or behind a nip i ( K i ) that corrects the registration error Y * / 1 i , suitably forward in that velocity - And / or backward direction by feeding appropriate signals via suitable transfer functions in the control loops or with the help of additional setpoints carry or track.
  • the signal additions and subtractions described for decoupling can not on the mechanical level of the system, but they have to electronic level, since they are not introduced to the mechanics can be.

  • the force F i , i +1 is not fully controllable by ⁇ i .
  • ⁇ i such a property of self-compensation must not be present.
  • ink and / or moisture is introduced during the printing process and / or when heat is applied, for example by means of a dryer in one of the sections before the nip i ( K i )

  • the force F 23 could be regulated.
  • the now subordinate control loop for Y * / 1 i ensures that the controller i.3 for Y 1 n essentially has to compensate for the disturbances that occur after the terminal point i ( K i ).
  • the superimposed register control loop i.3 is able to work together with other possible control variants for forces and partial register errors.
  • the setpoint value for the partial register error Y * / 13, w could also be influenced in a suitable manner by the register controller i.3.
